Confused...Please help me!!!?

I am about to break up with the most wonderful, beautiful guy I've ever met..someone I have been hoping for for a very long time who happens to be the father of our soon to be baby as well. This is all bec. I fear that I am going to get hurt. I have feelings I can't explain such as what if hes still in love with his ex - though he told me he isn't and thats a situation that can never be bec. hes in the states, shes in germany. Also, I am afraid there's an age difference between us.. Im 34 and he's 23.. a very mature 23 and in the military. He is currently deployed. We are both spiritual. We met, became friends, got pregnant, fell in love..... we have been friends since last yr but we just recently got pregnant and started dating. I have a problem with commitment out of fear bec. ive been cheated on in the past... but this guy makes me happy, touched, emotionally connected. I just love this guy- hes so wonderful but why do i feel this way??
