Actually my OH got someone pregnant while we were split up and I found out after we got back together by an anonymous text. She was his boss. Suddenly him never coming home from work in the latter stages of our relationship made sense.
I will probably never know the truth about what happened, but it doesn't upset me. I have accepted the worst case scenario and moved on because I know he loves me (my incident had nothing to do with retaliation or anything like that btw). It's called dealing with a bad situation in a mature way and accepting good people do bad things sometimes.
