Sex video chats 3rd time around

My husband & I just celebrated our 16th Wedding Anniversary. However, I have caught him 2 times in swinger chatrooms, sex video chats, etc. and have explicitly told him I DO NOT LIKE IT and I DO NOT DESERVE this behavior. He has promised never to go to those sites again, and GUESS WHAT? Almost 1 year to the date, he is back to doing it again. He has NO pride...he does it when there are other people in the house..but thinks I am NUMB when he all of a sudden closes the window. We have a 14 y.o. with special needs and I am at the point where I just want to smack him..and throw his ***** out of the house. We are in our late 50s, and are about to become 1st time grandparents to twins. WHAT advise can you offer?

Hello thirdstrike and welcome to PC! I am sorry you've come here on such upsetting circumstances. Maybe it is time you told him he either gets help for these actions and stops them or you will have to make some changes in your life?
You don't deserve to be lied to that way. I know how hard it is, my ex cheated and lied over and over and every time I'd forgive him because he promised to never do it again, but like you..a year later and he'd be back at it.
Some people are very very hard to change, but maybe if he realized what he could lose through his behaviors he'd be more willing to change.
I hope you can figure this out and be happy again

I am 55 and frankly, could not stand this sort of crap. I agree with above poster, he needs to get some help or you need to make some adjustments to your life. I know it would be very tough with a special needs child, but you have to live a healthy life for her.
I had a friend whose husband got addicted to internet porn. It got way out of hand. She stayed with him a long time because she was religious and didn't believe in divorce. She also had never held a job. So guess what? he up and leaves her! So now she is starting over..found a job and is living her life.
I wish you the very best and my heart goes out to you.
