My husband doesnt know yet but i am going to be filing for divorce soon. Unfortunately, we were in separate bedrooms for a month but now he's somehow weaseled his way back into the master bedroom. I can barely sleep at night and it's been awful. Fortunately, i have a decent support network around and if need be, another bed to go sleep in if i have to. Being under the same roof is enough for him to crawl under my skin at this point. Try to spend as much time away from eachother as you can, and only see him at night, right before bed... if that's possible. that's what i've been doing. Seems to be helping me at least get to sleep.
