Acceptance that you cannot control what he does or what path he takes. You can only control YOUR behaviors and YOUR choices. You can CHOOSE to plan an interesting, exciting, fulfilling life for yourself and your H can either decide to come along for the ride, or he will miss out - but you will be living your best life.
As for dealing with him in the home - as long as you're angry or negative he won't be interested in reconciling - why would he? MLCers worry that they won't be forgiven for their transgressions anyway. Put on a happy face, enjoy your life, be a little mysterious, let him wonder what you're doing and see you having a good time that he might want to join.
I know this is a bit harder in this time of pandemic, but do the best you can with it. If he still leaves - well, you're further along the path to your new life. If he reconciles - well, you still have an interesting new life for yourself, one that he can join in.
Now, on the other hand, if you're truly done with him (by the time my ex finally left, I knew I wouldn't take him back no matter what, that I could never trust him again, it was a three strikes and you're out kind of thing) then quietly plan for your divorce and getting into the best financial position you can for that.
