I'd be going back to where the support is before the baby is born as he won't have a say in that at all. If you wanted to move after the baby is born it would be a lot harder as legally he would be able to stop you and it wouldn't matter if you had no support or not.
If your not happy with how he is treating you know while your pregnant with his child I doubt he will change after the child is born.
A women's gut instinct is always right when it comes to the men is our lives or where in our lives.
Write out a list of pro's and con's but money cannot be apart of it at all as money can alway be a striving force to make some women stay with the man for the sake of it
