glad you are wanting to continue making an effort to stand up.
I will say, that a big part of his behavior since the holidays is from you. But, that is okay, because you are putting up the boundaries that you feel is necessary for you and your D. If you had continued being how you were before the holidays, perhaps he would still be acting as he was, or who knows, but the fact still remains that he is still not really working on himself and hasn't the desire to at this moment and so you need to set these boundaries, and he's going to hate it. But after time goes by, he is going to respect you more and more, but it's going to take a long time IMHO. but it will, as long as you stay consistent and are calm, and use wise healthy boundaries, and still be compassionate at a distance...if that makes sense.
I can see years from now that you will be the reason for him getting on his feet, and I really hope that happens, for you, for him, and for all of the kids involved, especially your baby.
I have changed since the holidays. Otherwise he would still be cake eating and trying to live the double life like he always has. He just pushed MGF aside for the holidays so he could make himself feel better and guarantee he wouldn't miss anything with baby..once that was over he went right back to his normal, horrible self. Reminds me of when I was within weeks of having baby and he decided to be this stand up guy (after I caught him with OW). He had changed his whole life, blah, blah! Now I look back as it being because he wanted to be assured I would allow him in the delivery room. Everything exh does is for a motive.
I don't know if exh will ever get on his feet. Why should he? He has everything he needs right now.
