I feel like I failed....

Im going to start this off by saying 1. Im currently 19 weeks pregnant and 2. I'm not perfect, nor have I ever claimed to be. I have ADHA and BPD, I have fucked up many times with jobs and have been in and out of jobs, I'm terrible with my finances, I have low motivation for A LOT of stuff including house cleaning and cooking, and my biggest regret is that I vaped THc around and while I breastfeed my son BUT never while I was pregnant. Again I know a lot of this is terrible and I wish I could go back and fix all of this, but I know I can't and I jave been trying to fix a lot of my mistakes but now its too late. My partner of 9 years wants to kick me out of the house and take our son away and then eventually when I give birth, he wants to take our daughter too. He says he can't put up with me anymore and he hates me and wants me out of his and his family's life for good. I've done my best over the past year to change my ways and my habits and do what he wants me to do like keep up with the house cleaning, be more proactive out of the house with our son, and try and get my finances in order and spend less, but nothing I ever do seems to make him.happy or satisfied. I've even disconnected and cut ties with my family cause he has said they are toxic, manipulate me, and have mooched off of us(partly true, but not completely) to were I've given them money that left me short on cash for our family. I've given all that I can to work on our relationship, I dont want to give it all up because of our shitty communication skills and I know we can truly make this work if we work on it together and not just point the finger and say its the others fault. Ive thrown couples therapy out to the table, but he just flat out rejects it and says I'm the only one that needs therapy. Ive point out that he has an anger problem and a drinking problem and that our communication with eachother is a good reason for us to go to see a therapist but he says is all his problems are because of me and that if I wasnt in the picture everything would be fine. I dont know what to do, and at this point he has all the cards in his favor. If he really does kick me out, I have no where to go since I chose him over my own family, his family has money so they can afford the legal side of things and take my son away, and he has a more steading EVERYTHING compared to me. I dont have any friends I can rely on since my friend are his friends, and like I said my family wants nothing to do with me since i chose to try and make my own family life with him work. I feel lile im just such a fuck-up and that I'm losing everything. I dont know what to do.....
