MLC or WAS, it does not matter, you are allowing him to run your life, you are allowing him to make choices for YOU. You have the choice to walk away, have the choice to say NO, to not listen and to remove yourself; you don't have to answer the phone, reply to emails or open the door if you dont want to, its your right. You You You. Haunted, you need to dig really deep and find that inner strength to stand up to your h or he will continue to steamroller you and cause you so much pain and hurt. I don't want that for you, I want to see you moving forward with strength and courage, I know you can do this -
You owe it to your d to get control of this. She is relying on you to have her back. Yes he is her d, but you can clearly see that he is not in his right mind and its your job to protect her from his crazy. Boundaries haunted, we as parents set them for our children, bad behaviour results in consequences, this is the same principal, treat h like you have another child to deal with.
I know its scary to say "no I am not going to be treated like this any longer" but believe me, its empowering.
Read up on going dark and no contact - I appreciate you have to have contact regarding your d but the idea is that you do not contact your h for any reason apart from an emergency with your d or if you need to speak about finances or visitation for d and you do not have a mediator to act on your behalf. You don't reply to texts, emails or phone calls immediately, you remove yourself from his life and the situation. It gives you breathing space to regain control over your own life and sets the boundary that you will no longer be at his beck and call. Any contact you do have keep short and on point. He will try everything he can to break you, he wants to be in control, this is where you have to stand strong and tell yourself that he no longer has any power over you.
Keep going haunted, its a minefield that you are wandering around, you are finding your way through it really well. I know you can do this, have faith in the process.
