Do YOU know what his rights are? Have you talked to an atty about it? If you fear for your safety, for instance, you could get a temporary order to have him barred from the premises. In any event, there are ALWAYS ways to set boundaries, Scooby -- you don't just have to let him walk all over you.
When my wife was having her affair (7 years ago; we have since reconciled), she came home once about 11pm after saying she'd be home much earlier than that. So I said something like "I was worried about you; if you're going to be much later than what you had anticipated, please just call or text me and let me know." Then, the next time she said she would be home around 11 and didn't come home until after 2am. So I shut of all the lights in the house, locked everything up, and turned the house security system on.
She got the message, and never did it again.
This is your marital home, not a motel. You can't stop him from having an affair, but you can -- and should -- lay some boundaries that would be more emotionally healthy for you and your children.
