A change from last time..... Any Help??

I've changed my preference in guys. This one is 21, is on a break from his last girlfriend and could be a dad with her. Yeah I pick the wrong guys I know, but he likes me, proved it on friday night. I'm just confused, and frankly a little bit worried about whats in store for me over the next few weeks. I seriously love him but if he's gonna be a dad theres nothing I can do. I just don't wanna loose him ya know. Anyways, give me some feedback.. ideas and what not. Need to think of what to do.
