Parking dulu with murtabak, for interesting info to learn here.

1: Denial, no. Attracted mah... Can't change the fact that you are attracted right?
2: Fight? Depends. It's like how you have a certain affinity to some food, and others you try to avoid. Gotta ask yourself about it.
3: Follow your heart? My heart tells me to smile subconciously whenever i see that person, whenever she talks, whenever she smiles. Am i attracted? Yeah. Will my heart push me to pursue this person? Most probably not. Reason being she's not the one that can help fulfill my life goals.

Still doesn't change the fact that you are relating to a person, an individual , whenever you establish a certain communication with them.

Still gain some mar. Albeit newer a bit la.

Thankfully, i can empathize with most LGBTIQPA people. Compared to LGBTIQPA people, there are people that completely goes against the law of nature and science themselves. Almost too baffling to be true. And even if you share with people, they raise their eyebrows as high as the ceiling. So, yes. I can empathize with people wanting/avoiding to come out.

Firstly, you are at a crossroad. Not telling her, you have to deal with all the feelings you are having, and it is only going to be time before they take over you and blurs your judgement. Telling her might cause her to steer away from you (or at least i think that is how you feel it would go down). Which means rejection towards your honest feelings, leaving you vulnerable and broken. That fear itself is causing you to have doubts. We've all been there. Every single one of us at some point.

Your situation is very similar to a kid sitting by the piers with the doubt of either jumping into the river or not. Tough decisions to make and all. But you have to be the judge of it. If i were in your shoes, i would tell the girl. Why? Because why not? Keeping it in is never good. Too hasty and it all goes to hell. Just tell her in your most honest words. Sit her down somewhere and talk to her. Refer and relate to her as a person, not as an object of your desire. Tell her all that you've been keeping in. Share with her how it makes you feel. Do not expect her to reciprocate your feelings. Most people will freak out. Expect that. But it is not something unheard of to have feelings for the person who you associate as same sexuality as you.

Then, allow time to let her sink all that details and information into her thoughts. Do not rush her, and let her judge and decide by herself. It is a good practice to leave telling her your feelings as a heartfelt "heart to heart" talk. Instead of a confession of guilt, that by having feelings for her is wrong. (which sadly most guys of malaysia seems to do). Then go on your life like normal with her. Don't try to treat her any different, in the hopes of it helpign your agenda. She will show you how she will deal with your feelings in due time. But the most important thing is to tell her, let her digest, and react with her reaction. And don't be disappointed if she rejects you. Take it as an experience worth learning.
