Can this relationship last like this? I recently fell in love with a handsome and intelligent university student while I was dressed as a girl after being persuaded by a friend, and I am wondering how this is going to work.

Your question is pretty vague. So, you dressed up as a girl, and you're really a boy, and fell for a university student that's a boy?????  And now, you have feelings for him?

This sounds like an episode of Catfish.

If you want to have a relationship with someone, you have to be honest. If you tricked the other person by dressing up as someone else, how do you think this is going to work out once he/she finds out what you've done?

By pretending to be someone you're not, you've set the other person up to be hurt once they've found out the game you're playing.

Two pieces of advice - (1) stop trolling. (2) stop pretending to be someone you're not. No one wins in this situation.
