Let say you met a girl, at first it was nothing special, just another friend. It might be someone at work /  school etc etc.. You yourself start to befriends her because she is friendly / charming etc etc. You CONSIDER yourself close to her as time passes by. The regular sms-ing, joys and laughters, outing & whatever both of you did to fill in the time. Simply put it, she’s a large part of your lonely universe. Then the inevitable came, you started to develope some feelings towards her. You can’t deny it and deep inside you know it’s there. At this point, you wanted to tell the girl how you actually feel. BUT.. you still hesitated on what to do.

Before you do anything, consider these...

1.MOST IMPORTANT, make sure she wasn’t in any relationship. But if you still just want to confess to express your true feelings, please do so but remember, she’s in a relationship already, and you’ll know what her answer would be right? As long you’re WELL AWARE of that...
2.This is the hardest part: “Measure” yourself thoroughly and be honest with it. Do you look pleasant enough in her eyes to be her EQUAL partner? Please forget nonsense like “beauty is in the eye of the Beholder”, because we are NOT the Beholder. Human beings are superficial creature and it’s the inevitable truth. 90% of the women who rejected me, it was because of my looks. They’ve said otherwise but I know better. I see the mirror everyday for Heaven’s sake !
3.Are  you sure that she’s romantically interested in you? Be clear and don’t be absurdly blinded by your feelings for her. For all she’s aware of, you’re just another good friend or worse, kinda like her “big brother”.
4.Are you sure the two of you “had a thing” going on? Please keep in mind that certain girls are just born with happy go lucky-supersocialize DNA embedded in their core system. They can be way over too friendly to guys, without ever THINKING about the slightest possibility that their friendliness might be interpreted as something else. Maybe you feel that you “had a thing” with her, but are you sure your the only one for that matter? She could have plenty of male friends surrounding her life (especially the pretty girls, they always do).

And if you’re rationalised all those aspects and ready to confess, please consider these before you do. Because after you confess, there’s no going back.

1.ALWAYS prepare your mind and soul to be rejected. Again, be honest with yourself on this. You’re now in a state of “dizziness”, as your feelings for her couldn’t be contained and you want her so bad. In a state like this, rejection will kill your guts and it would take a long time to recover from it. You might feel betrayed. You can save yourself from future grief and agony if you step back now. DO NOT confess if you can’t honestly accept her rejection.
2.Let say you can live with being rejected. How will both of you handle things from there onwards? Like it or not, the situation will be affected. There will be awkward moments for the both of you. If both of you don’t deal with it seriously, you can feel she will part herself from you, and suddenly you realise she wasn’t the person you once knew, and she will disappear from your life. The possibility of losing a friendship is inevitable. Let say you can honestly remain friends with her even after rejected, but can you say the same about her?
3.Let say both of you CAN remain friends afterwards, how would you honestly feel to be around her everyday? Being able to see her, keep in touch with her, but wont be able to have her in your life as you wanted her to be? Can you live with that agonizing feeling every single day while still harboring feelings for her? Then the day she met someone special, the day she got engaged, the day she got married? Can you TRULY & HONESTLY be happy for her?

All things put into consideration, if you still want to confess, by all means go ahead. Congratulations if you were accepted but if otherwise, I seriously hope you’ll 110% prepare for the aftermath. It’s best to keep the feelings for yourself and bottle it up, because if you can’t deal with her rejection, things might get ugly for both of you.

Let say you befriends some guy from your office / school etc etc..You treat him as a normal friend and as time passes by, you got closer to him. You feel safe with him, and he seems like a “big brother” you never had. The friendship you have with him was great and you’re comfortable with it. You still keep on in touch with him even after parted ways, sharing your ups and downs, you feel that he is someone you can trust as a friend, a very good friend that you can share anything with. You however already in a relationship with someone else, and he’s well aware of it.

Then suddenly, out of the blue, he confess his true feelings for you - That for some time now (perhaps years), he started to have this feelings inside him that is more than a friend should have. At that moment you was shocked beyond belief, and it’s very likely for you to reject his wishes. Here are some things I would like to point out :

1.PLEASE don’t feel betrayed by him. It is normal for a guy to fall in love with a girl. Especially guys with never once had a girlfriend in his life, and you are a large part in his lonely universe.
2.Remember that it took him a lot of guts to confess it to you. He might even do foolish things to get it there at that stage, to let it out loud. He might seem selfish, knowing you already in a relationship (if you are) but the truth is, the reason he confessed to you is because in 5 years, or 10 years from now, he don’t want to live in regrets for not letting you know how he truly feels for you.
3.If you’re single, and he can accept your rejection and willing to remain friends afterwards, please do so -  remain friends. Don’t let his confession as a setback. Yes it will be awkward with him, but time will make amends to it. Why sacrifice a friendship for this incident? Just keep yourself a certain distant from him afterwards, because seriously seeing you too much would hurt him. He will understand if you want to keep a certain distant. Just try to not forsake him completely. BUT...
4.If he slowly seems to grow apart from you, then maybe it’s the best for him. Because he’s too much in love with you and he couldn’t bear the thought of being “just friend”. Seeing you would hurt him as much, and he understood that it's his fault and not yours. You just being a good friend all this time and somehow, God planted the seed of love in his heart for you. Remember he doesn't blame you for what happened. Believe me he still wishes all the best for you in your life, and your memories with him will always be something he treasures the most. A true friend will never have an ill-will for someone he truly loves. The costs is this – you’ll might never heard from him again. You might hate him because of that but that’s a possibility he have to live with..

For guys :

1.Always keep your reality checked. NEVER get too close with a girl that is way out of your league / in a relationship. Sure at first she will be just another female friend, but if you don’t put your barriers correctly, you might start to fall for her. It’s best to keep a certain distant from her. Sometimes, to be nice to ourselves is to be cold to others.
2.If you start to feel something out of the ordinary, please tell your female friend immediately, before it’ll grow into something else entirely so she could “act accordingly” after that. YOU DON'T WANT TO HARBOR those feelings silently for too long.

For girls :

1.Please be aware that the possibility of one of your male friends might fall for you is VERY likely to happen and is inevitable. So please don’t get too close with your opposite sex, especially those inexperienced one / never had a girlfriend before. You might think that "i'll never gonna fall for him, so there's no worries" and see him as a normal friend but can you say the same for him? Who knows right?
2. I dont' know whether its true or not, but people say that a girl can "sense" if a guy starts to like her. If you do, please "act accordingly". DONT EVER give any gestures that might be interpreted incorrect by him, else it would be a false hope for him in the end.

That's all I guess. I hope it would be a good tips for those who was thinking about to confess to someone. Be sure and understand of what you're getting yourself into, because there's no undoing it. It's okay to try rather than guessing and bottling it up to yourself but my point is be ready for the aftermath of your confession. It might ended up well, or it could be something you wished you haven't mentioned at all. The choice is yours to make, and the consequences, you'll have to live with it..
