It is obvious he is not interested in stepping up to be a decent partner and father along with the fact he emotionally blackmails you, i.e. he gets resentful when you let a sitter take the baby for a while. He stays out all night supposedly "working" and is completely disrespectful of your needs and wants. This is no way for you or your child to live.

The soundest advice you have received here is telling you to go to your friends in Montana even if it means having to throw away everything you have been working so hard for. You can only stay in a holding pattern for so long.

Be strong
