Hmnnnn. .
This is quite weird. Honestly, I myself am having relationship issues and u might not want to follow my advices nor listen to my opinions.
However, there's just a few things I would like to say. To be honest, when a girl can be so strong and make a decision, walk away and start ignoring u could mean she really means it. COULD ya. From what uve mentioned, she seems like an insecure person and u showering her with love would only make her more secure. Maybe that's not what she wants. Maybe its the emotional support uve given her and u being there for her always made her feel that she loves u a lot. It could just be the "cling". Have u ever asked her why she always has to hide around when with u? If she has a valid reason like family objects her dating or something then maybe u can accept that for now. I mean, a relationship is between the 2 of u. There's no need for the whole world to know anyway. From a female perspective, I suggest u take a cool off period. During this time, don't contact her. Give her time to feel the lost while u take ur time to really think if this relationship will work out in the future given how it is today. Once u get a clearer picture, u will know what to do next. Sometimes, there are females that love attention and just do all these stupid things only to regret later. Who knows right? Think about it. . if she is that kind of girl I mentioned, would u still want her back anyway?
