We have 2 teen boys together but for 90% of their lives he wasn't around. This year we got together and were being a family but he messed up (cheated). I haven't see him in 3 months but we didn't split up till a week ago when I found out. i didn't give him a chance to explain I just hung up. I am not sure if he will or text.. but should I even respond? I know we have kids together but he hasn't even asked about them and my 15 yr old hates him.. my 16 yr old has special needs and he loves him because he doesn't know any better.. should I never let him come back in our lives again? He likes the fantasy of a "father " but not reality.
