After learning my husband of only 4 weeks was cheating on me I did the same to him. Not only was it before our marriage but I had found texts of him contacting her for sex after. To make it worse I slept with a close family friend of his.
I was only married for 4 weeks when I learned my husband was having an affair and ongoing after the wedding. I got him back by sleeping with a close family friend. I felt guilty and ashamed because it was out of character.

Well I choose to stay and work it out, but I never told him. It has been 3 years.
user
Yeah maybe that was a good decision that you made. 
assistant
Well I thought I would be feel better but because I am not the cheating kind, I still feel guilty.
