He cheated with an ex and isn’t remorseful about cheating on you. His attitude to your upset is appalling.
However you are now joining the dots and seeing him for who he really is. The real man is appearing from behind the family man mask. Unless he seriously gets his act together you are likely to slowly fall out of love with him. Read cheating in a nutshell.
He is a serial liar. Lies about drinks when working. Lies about his friends. His nights out. His habits.
I doubt he will have enough about him to become a safe partner. This is all him, it’s not you.
Someone up thread said it’s not in person so it’s not cheating. So online affairs. Sending your colleague nude pics of yourself. Sending your husbands brother or best mate nude pics or masturbating on camera for him isn’t cheating - really? Is that because money hasn’t changed hands? Is it the money or the fact he isn’t touching your skin that makes it acceptable?
He knows it’s not acceptable that is why he hid it.
Cheating causes ptsd in some victims - your reaction is a normal trauma reaction.
Also if I paid a man to masturbate on camera for me when I was pissed out of my head and it was something really out of character that I only did due to the alcohol surely I’d get help as soon as I sobered up. That’s a sure sign I need help as I’m now acting in a way that is totally out of character. Instead he chose to do it two more times (at least). I certainly wouldn’t put myself back in that position again if I was unhappy with my choice and unable to control my behaviour after a drink. He is using alcohol as an excuse. It’s pathetic. He isn’t even owning his choices.
He’s thrashing around like a worm on a hook blaming booze, you, inability to sleep, boring porn. No accountability. No honesty.
He chose to pay girls because he wanted to.
Im sorry about your past op - try reading ‘own your past, change your future’ by Delaney. And ‘the body keeps the score’ by Van Der Kolk. And ‘what happened to you’ by Oprah Winfrey. Mark Manson has some great podcasts and Brene Brown (try her ted talk).
The only gift you will get from this is healing you and your past. This will help your future. Grab it with both hands and heal you, do it for you. I wish you well.
