Hey, OR. So strange. I think you are doing the right thing. I always think you have done the right thing. And I don't think full custody is out of the question for you, either. It is really strange that he is coherent in other venues.
Sometimes, I can't believe my ex; what he does, what he says, how he treats the children (and me!!). But even though I am in the midst of legal garbage with him...I realize how much happier I am and how much closer to my goal I feel I get, when I can say: "Weird, pathetic loser".....and then let that scary energy go...and move on to thinking about my wonderful life instead. I can get really down and dark thinking about all the what if's and focusing on his actions or potential actions (what I don't want!) and I see that I can get really happy when I drop that catastrophizing and just realize how much nicer my life is ....simply because I am not married to him!!! That alone, makes me a happier person. so when I focus on what I do want, I think it brings that reality into perspective for me.
Naturally, we have to be smart, realize what we are up against, stay on our toes.....but we can do this AND be happier too.
Anyway, I think you are seeing that in your life. It's pretty clear that you are moving in a direction and picking up momentum that cannot be stopped, as Longtire pointed out.
Best to you, OR (my hero...still!!)
