My (40f) husband (39m) admitted to me that he has been cheating on me with his cousin for a majority of our marriage.

My husband’s cousin recently was killed in a car accident three weeks ago. This has made my husband visibly depressed and a lot less like himself lately. Tonight when I got home from work he had our two kids go spend the night at his mother’s place and had made us dinner. After dinner he sat me down and told me that I needed to prepare myself for what he was going to say.

He then proceeded to tell me about his affair. To sum some things up he essentially had been doing sexual things with his cousin since she “seduced” him when she 13 and he was 16 This sexual activities went on through their adulthood up until he started to date me. After we got married things didn’t happen between him or his cousin until around 4 years into our marriage when sheWe’ve been married for a little over 15 years for context. This has continued up until 3 weeks ago as you can imagine.

He told me to take it as I will and he’ll accept anything I choose to do considering our marriage. His cousin apparently was a lot more than just some sex fling.

I’ve never would have expected my husband to be cheating. He never did anything that would give it red flags like coming in late or leaving hair of another woman around. I’m at a standstill and not sure where to go from here. I haven’t been able to say anything to him after he was so blunt about it. I’m still crying some now, I don’t know where to go from where.

Any suggestions are welcome.
