Do men reallly go to other women for comfort when they have been dumped?

I left my husband for 6 months. All he did was hang with the guys and was unappreciative of me. we have 2 children together as well 8 and 4 and I just couldnt take it anymore. We are very young and thought maybe it was for the best. During our seperation I had no intention of ever being w/him again and we both started seeing other people. He would come to my house call and drive by all the time begging to come home but I refused and encouraged him to be with the other girl (a stripper he met while she was working) I never judged her and talked to bout meeting but my husband wouldnt let it happen and he wouldnt let her meet our children either. She had kids herself and my husband somewhat played house with her but didnt quitoing out every night and weekend and as he called it drinking his pain away. She ended up pregnant they split up soon after and we ended up back together. We have had alot of marriage counsling and things are good our future is bright. But I cant get over her having this baby. She decided to adopt the baby after she found out we were togethrMy husband says he wants to leave it alone and that the baby will have a better life this way. their are 4 possible fathers as well. He says his relationship with her was simply him trying to stay saine while we werent together and it meant nothing. He did cry hard every time i saw him and always tried to come home. We have our final baby on the waynow and he says hes excited. but i almost feel as if I am replacing the situation for him. Is it possible hes content with her decision to adopt and their relationship was really just him trying to feel better?
