I've been married over 4 years, known my so for 6 years. It wasn't until we moved in together I had found out my so had sex with his cousin. I had found nude photos of her in his email and a many chats that confirmed they had been together. The other thing is that they said they loved each other and hoped to be together one day. I know my so had said that to more than one female so no surprise there. This happened before we settled down so I just decided to move on. We had a child and my husband started working overseas 9 months out of the year and has done this for 4 years. Well, recently I found out he has been emailing her for over a year and a half. She is the only family member he does talk to besides his mom so it just seems a little odd plus from a secret account hidden from me. I don't see how it could be physical at all because she lives so far away and his time stateside is limited. They don't say I love you to each other either plus she is in a serious relationship with someone else. Would like some outside input.....TIA
