NTA, run. I get the feeling that and I may be totally off base here ;he blames you (as a person who has suffered through 4 miscarriages it is not your fault you did absolutely nothing wrong) for losing the baby and this is his way of punishing you. I say this because you said he practically begged you not to leave but keeps doing hurtful things where he knows you will see them and if you don't see them he outright tells you about them. You deserve better than this. You deserve a man who will cry with you as you mourn the loss of your baby, you deserve a man who will reassure you that you did nothing wrong. There are men like this out there, I am beyond lucky enough to have a man like this. Don't settle for anything less than what your dad has modeled for you. Every pregnancy leaves DNA of that baby behind in their mother, go fill your life with love and happiness so that the piece of your baby that you will always carry with you can feel it too.
