Yes.
I did it, and I'll tell you why.
I married young at 21 after being with my ex since I was 16. I thought he was the love of my life.
After we married, he became abusive. Verbally to start, then physical. Everyone was commenting on how poorly he treated me. After over a year of this, I snapped and had a mental breakdown.
I cheated numerous times, with numerous men. I didn't feel anything as I felt numb to what was going on at home and was trying everything to try and feel some type of affection.
He found out because I told him. He gave me another chance but used it against me and the abuse escalated to the point I felt exactly the same again. So I left him this time.
Despite the cheating, I loved him very much and I wanted him to change so we could have our "forever". The lesson I learned from this though, is that the second I feel like I need another man to satisfy a need, I will leave this time instead of contributing to my own mental breakdown.
I've had a few relationships since that I have never cheated in so I don't believe that "once a cheater always a cheater" also.
I do feel bad for what I did, and at times I grieve my marriage loss. But he wasn't good for me, and I turned into someone I thought I would never be.
