Yes, i know i sounds like a bad guy, but i just couldn't get this girl out of my head. we talked few times, i do not have her number yet. the moment her friends told me she has a boyfriend already was my most heartbreaking moment. and i'm still heartbroken. yeah i don't know what she's done to me lol until i'm so crazy for her.
Mostly the advice i received is move on and find another girl. i don't know what i can do or what should i do. anyone has experience in this kind of situation can offer some advice?
She didn't do anything to you. You did this to yourself.
Let me guess you met her and immediately liked her. So after that you went home and started thinking about her (FIRST MISTAKE!). Then you started to fantasize about what it would be like if she was your girlfriend, how life would be nice, etc.. (SECOND MISTAKE). You probably did this for more than a couple of weeks. You basically programmed yourself to fall in love with her even though you do not really know what she is like.
This is a common mistake made by young guys. Falling in love is just you doing it to yourself no matter the circumstances. Falling in love is a mental state you put yourself into. Maybe when you realize this you're going to be able to forget her and hopefully you don't do this to yourself again.
Consider this one of the best advice that has been given to you.
