TLCRN:
Yea it was pretty awful...especially since he borderline stalked me and kept a notebook of everything I did...where I went..who I saw. I did my best to ignore it and just kept at my life.
I'm not the only one either. Like I said, there are literally thousands of separated (and often hostile) couples living under the same roof due to money, custody, or home equity and there's nothing you can really do about it.
A lot of these situations turn really hostile with people calling the cops on each other, etc. I handled it as best I could ..luckily the house was relatively large so I was able to segregate myself and would leave on days that he was staying...like some weekend days and try to sleep somewhere else. When I was there...I had a door lock and a special kicker wedge which blocked my door so it couldn't be pushed open. I had to wait until he finally agreed to sell...then I had to wait for the closing. It was tough and was the worst part of the divorce process for me...luckily its over now and I'm in my own home. I remember the first night I slept in my new house...it was amazing. I love coming home now for the first time in about 20 years...so for me, its been well worth it.
For this OP though, I'd get a medical note and see if there's any way to get exclusive possession because of health reasons. I've heard there are cases of that...where if the stress of living together is causing you extreme medical stress, you can apply for exclusive possession. I'd ask my lawyer about it at least before I just moved out.
