Hiya, it’s good to hear from you.
I guess if it’s making you ill mentally and giving you bad anxiety, then you need to just focus on your self. Because I guess the kids will notice it. If you are not with him, then he needs to get the support from a C. A or A. A group. I can’t remember what his addiction is. But I guess they are all the same. My ex now was sort of supportive when I was with her. And has not asked how I am or any support what so ever since May when we split up, and it doesn’t bother me. I need to do it for my self and I get the support from my groups, my new friends in the meetings and close family.
So me personally if he is a good dad, just deal with him regarding the kids. And you go and focus on you.and let him focus on his recovery. Hope this helps.
