It might be obvious to point out, but I want you to remember that going over to their house to meet his wife is completely different from spending time alone with him in their house and having sex in their bed, and that it's okay to feel differently about the two things.
On another note, while I think you may eventually be comfortable being in their house, it is completely okay for you to have the personal boundary that you don't ever want to sleep in "their" bed. Bedrooms can be such personal spaces. I'm very open, but unless I'm invited in by all parties I do not like even hanging out in people's bedrooms, let alone getting intimate there.
I think you're doing great. Keep talking, keep thinking, and feel free to PM me if you just want a sympathetic ear.
