Yup... lots of pressure from a lot of angles... I can't see him pursuing the affair in a cramped home full of noisy kids...
Just don't take him back immediately.. set your boundaries and set the wall high
1. No contact agreement 2. Full transparency 3. Family therapy twice a week 4. All contact with OW is ended completely
Long term you want to get yourself in a better position there.. get your name on the home etc...
I think with a cramped home, screaming kids in his ear, a lawyer after him, and his work padre harassing him he's lot a lot of pressure to deal with not to mention whatever you posted on facebook...
Keep the ball rolling and he may fold
Even if you don't want him back you can get him to TRY to come back... And in my opinion ALYWAYS reject his first offer
