Even though we had many problems in our marriage, I trusted my AH completely. We were together 25 years. Then he had an episode and I had to ask him to leave until he got help before he hurt me or one of our kids again. During the time I thought he was trying to get himself together he was living with his best friends wife, his best friend was working out of town. She had a drinking problem also. During this time they began an affair. Last July she divorced his best friend and they are now living together in La. Even with his drinking problem I never would have believed he would have done something like that. He and I are still married. He is not the person that I met and fell in love with 26 years ago, but I can't say that I don't still love the person he was.
No, I don't believe that all A's cheat. I don't know what the reason is for the ones who do.
