Should I tell her how I feel or I wait?

I would tell her but I do not trust the internet dating things people could be making up pros and pretending. Tell her but be careful cause you never no. In my school these boys made up like 3 girl accounts and actually had all the guys fall in love with them.

Well "Hearts are broken with words unspoken" But of she is in a long-term relationship. Maybe not. You could risk it and see what she says. But you may get turned down. It depends how the girl is. If she is a rude person. She could end up hurting you really bad. /so be prepared for the worst if you do end up telling her. Maybe get one of your friends to go on this online thing and meet her and see what she thinks of you?

Don't say anything, but do do something when you're together that hints that you're interested. She'll pick up on it. With the LDR though, they almost never work out. I would have said be the guy that catches her when it does end, but in reality she's going to dump him because she wants to see someone else. My advice is be that guy she breaks up with the LDR for before some other guy beats you to it.

Yes, you should tell her. what's the worse thing that's going to happen?
