Need advice

Have 4 kiddos, currently expecting #5. I was done at 4 and so was my husband. I was on bc pills and took them at the exact same time every day! But still got pregnant (happy and excited for the baby now) Husband agreed to a vasectomy, had the appointment set up and canceled. Said he doesn’t want to “go through any pain” and that I just need to go in and have my tubes tied. Which, I did NOT want bc but I used it anyway, he will not pull out and he will not use condoms! So I’ve done my part. Not to mention I’ll be taking care of 5 kids and it’s a lot harder on the woman. What do I do? I do not want bc again because well, I got pregnant anyway and it also depressed me really bad which he also said if I didn’t get on pills for depression, he would leave. So I did that too. Yet he won’t do anything for his part. Help what do I do? I told him we won’t have sex because this isn’t fair that he’s not willing to do anything to prevent pregnancy himself. He’s so selfish when it comes to so much that I’m over it.
