To give my experience, exh kept our house during a very long and difficult divorce. I had to leave because I wasn't safe with him.
He did not physically abuse me. He had mentally, emotionally and financially abused me but it took me until I was away from him to see it.
Leaving the house was a difficult position to be in when trying to resolve the divorce. It definitely puts you at a disadvantage but it simply wasn't safe for me to be there and he wouldn't leave.
Above all else @Selfhatredandshame BE SAFE.
The only regret I have is I had crap solicitors who said a non molestation order would be hard to get.
You sound like you're being fairly sensible but if I was you, I'd be keeping the evidence you have found so far elsewhere. Create new email account, get a new device, set it up away from home wifi.
Get a grab bag with your documents and emergency stuff in it, just in case.
People under pressure can react unpredictably.
I would check all the stalking behaviour out with regards to a non molestation order as part of divorce and try and get him out of the house.
Obviously that's temporary while you get your own place sorted and the house sold.
I'm sorry. It's very hard.
