Which guy should I go out with?

Right now I am really confused what to do…I am liking two guys and I am confused what to do about it. The first guy I like I have known for 3 years now and we have dated for a year and then we broke up for a hour and now we are talking again…the main reason we broke up is because he was immature and not a good christian…so I went away to college and decided to be a better christian and found a great guy who loved God. So I put my ex out of the picture and now he is back in the picture and I am not sure what to do. The second guy I met in college and he is everything I want in a guy a great christian and I really want to get to know him better. But the only thing is that I don’t know if he likes me and he doesn’t really show me if he does, and I really would like a chance with this guy. So I am confused do I give my ex another chance to show he is changing and willing to go to church more, and start over. Or should I go for this new guy that I don’t know if he likes me at all and I could waste my time waiting for a long time. I am really in the point of my life I would love to find someone to settle down with and just start thinking of a long term relationship…so what do I do go for the new guy I don’t know how he feels or go for the ex that I have known for a long time but we did break up and there are some questions still left?
