I am a married with two kids, 3 and 1yo. Relationship in our marriage has always been so-so, but we managed it so far. Our sex life was 2-3 times a week, until recently, when we did not have sex for about a month, firstly I was too tired, then he was away for 2 weeks, then I rejected him because again of two weeks managing kids on my own. The next date after rejection he registered with a dating agency. Obviously, he doesn't know that I know... Since then, we revived our sex life, even quite intensively, but he is still on the dating website emailing other woman for casual relationships. He does not have a clue that I know. What do I do now???
(this is the first time in our 5 year relationship)
