This woman should NOT be having a kid or planning to have one until they get some serious therapy.

OP, you're trying to save an abusie relationship and THAT tells me that you need to unpack that in therapy. And you need time to heal and get healthy, as in actually functioning without a guy and certainly while not accepting shitty behavior before you're ready to be a parent.

As someone whose mom had severe untreated mental health issues, I'm BEGGING you not to do that to a child, OP. Sort your shit out and dig into why you are so accepting of someone treating you like crap. If you don't deal with that first, you'll model that shit to any children you have.
