No. You can't go. You are needed here and I think you still need this forum. One good thing about all this is you can finally give up hope and fully emotionally detach from your marriage. Let it go, let him go, let all the ugliness of the past go and move forward in your life. Time to get away from all the drama of the past. Stay away from H and his personal problems for now and work on the D details and ensuring you and your daughter have a secure future. If he wants to talk tell him relationship talk is OVER, now it's D details only. You are focusing on your future. All that past sh!t is over. You have already heard it, you don't want to go over it anymore, no apologies, no talk about it.... you are moving forward in your life.
Put the cr@p behind you.
P.s. It's a waste of breath and energy to try and convince anyone they are in MLC or that a marriage a WAS wants to leave ever had anything positive in it. Don't even bother. In fact, it's best to agree it was bad and leave it at that.
There is no arriving, ever. It is all a continual becoming.
