Cheater cheater...

My husband and I have been together on and off for 11 years, raising 3 kids.

He has a history of cheating before we were married 3 years ago and we were able to work through it and trust was being rebuilt.

HOWEVER, this last week I found he has an account on the cheating website Ashley Madison. He lied and claimed it was old from before we were together, however the last logged in date was from a month ago. And the account was made at the beginning of 2019. And also admitted he's had several thoughts about finding other women to sleep with in the time we've been married

I feel absolutely crazy for being as upset and hurt as I am because he keeps telling me it's not as bad as if he slept with someone and he had no intention of meeting up with or sleeping with anyone... yet he has that account made specifically for that purpose...

Has anyone else been here or has any advice on where to go from here or even a good old "you're not crazy"
