Which girl should I choose?

I have a rather large problem. Two girls like me, but I only like one. If it seems simple, its not. I just broke up with the one I like a few months ago, and we had gone out before that. She also doesnt like me as much as I like her. On the other hand is the girl that likes me. I look at her as a good friend, but she wants to be more. Whenever im with her I make her laugh and I like to make her happy, but if I go out with her I would be sad. I don’t thank that I could realistically get the girl I like without a lot of luck and time, so that’s a factor too. also, lately I’ve composed some poetry about it, and this one kind sums it all up.

Her heart or mine? With those sad blue eyes She looks at me so That I cant hide the lies.

I don’t want to hurt her, But my heart screams out too. “You must take the other, You know you want to!”

I make her laugh But she does not make me. She gives me her heart, And from that I flee.

Her heart or mine? Should I pursue my love? Or make this girl happy And give my heart a shove.

Please help!
