I 37F was with someone 39M for 3 months when I found out he was married with a kid on the way. I found out it wasn't the first time he cheated during their relationship either. He cheated also before they got married. The guy is a compulsive liar. The reason I didn't speak then was that his wife was pregnant with their kid and I didn't want to cause any harm. Now I found out they had a second kid who is one. I myself moved on of course and my own kid.
However my conscience has been eating me up all these years. Should I speak up anonymously?
