Is she in the master bed? If so, that's where you belong. I'd move back in and keep to my side.

I was in the guest bed room for a month or two, because of my actions one night. I told my W I was going to earn my way back to "our" bed. After a couple months of being a model H, I announced I was returning one night. W decided to take the guest room. This obviously wasn't my goal, but at least it showed I was willing to stand up (and go to bed, lol) for myself.

M: A really long time.
Crisis: 5 years.
She's still worth it.
