Welcome to Gaia! ::

Im not a shy person but I really liked this girl and she liked me too but I didnt know so after waiting for her foe almost a month I got with this guy I broke up with him because I really liked her but it was too late she moved on. I found out in poetry club that she wrote a poem about me moving on so I tried to get with her again but she was with a guy...She is truely the oly girl i liked like this because I havent given many girls chances... two to be exact but what shoul I do.
I think she is happy so should I leave i alone???

Well, ive been in a similar situation.

Well, why dont you let the girl be happy? If she and that guy dont work out then you will still be there. : ) Give it a chance though because you dont want to ruin anything for her.
BUUUUTTT if/when they break up go and tell her how you feel! <3
if she liked you too then its possible she still does heart

You should tell her in an indirect way. Its always easier that way and since she wont be put directly in the spot light it wont stress her out as much. Like call her and tell her how you feel or message her online. Make sure you tell her that you realize shes in a relationship and you don't want to break them apart but you wanted her to know that you still have feelings for her. That way you don't seem like the bad guy.
