Mike, I am sorry. Really I am. I did the same thing to my ex-husband 21 years ago after the birth of our son.I knew I felt differant after his birth but back then it was called "baby blues". And you were suppose to just get over it.21 years later I live with the biggest regret of my life.And I pray everyday that he has forgiven me. He was a good man,husband,father. But unlike alot of woman I focused on nothing but my son. He was my life. I forgot about everyone eles including my ex-husband.I broke his heart and I pay for it everyday now.Good luck and hang in there and I hate that saying "I fell out of love with you" or "I love you but I am not in love with you". That's hogwash. That don't just happen.
