I’m very sorry op.💐
It’s hard to believe right now but you will be ok.
It’s very difficult and takes enormous strength but go grey rock.
Do what CurlsnSunshinetime4tea says
Get some emotional support elsewhere (therapist, friend, family) but show NO weakness in front of him.
Blindside him in turn by being cold, efficient, distant, and outwardly emotionally self-contained. Do not cry, beg, or be needy in any way.
Immediately stop doing anything to accommodate him in the house and encourage him to leave (if he hasn’t done so already)
Start reorganising the house, and the household schedule, to totally suit yourself.
