I've been reading along and I'm sorry you're back to this dodgy place with your H.
There is nothing wrong with enforcing boundaries that are in place to demonstrate mutual respect.
When your H came home you guys agreed to do some things to rebuild trust. You've done those things, H stopped doing them when he changed his password. He is disrespecting you and that's not OK.
Who knows if the relationship with FB/HS friend is appropriate or not. It doesn't matter. What matters is that he has disrespected a boundary you guys put in place so you could start to rebuild your relationship and trust.
There is some good stuff over on newcomers about making and maintaing boundaries. I really recommend you have a look at those posts by Puppy Dog Tails and others. It's OK to enforce your boundaries. It's healthy to enforce your boundaries.
As far as going out with her family and your family - I wouldn't be going there either.
Take care, you are a strong woman and you deserve your Hs respect and love. Keep reminding yourself of that.
Take care, V
