ok here goes...
I sort of scanned what you wrote ... there was one word that all you have to is say and explains the rest. "resentful"
If you have any resentment to him, you relationship is doomed if you don't seek professional help. If you really want it to be over, and I believe you do, then this is a perfect time. your baby is young enough that this will not effect "it" as much as it would when the baby was older like 5 or 6.
He needs to get a job. I am not saying that a stay home man can't do the work, but they have to be at least willing to try. He doesn't seem to care.
He sounds like he needs to grow up. Temper tantrums? Thats what kids do. I would tell you to go to counsleing but it really sounds like you have made up your mind. You can try and tell him that he needs to get a job or get out but this doesn't always make things better.
If it were me, I would tell him to leave. I would put my child in daycare, which sucks, but I would do it to make me happier and the babys future better. This is only my opinion. First and foremost , you need to decide what is important to you. If your quality of life is as bad as you say maybe it's time to consider your options. Good Luck!
