Advice please!

Okay so here’s the thing, I’m currently 14 weeks pregnant with my boyfriend. I live at my sisters because I can’t afford a place on my own. She’s giving me 10 months to move out, and I can’t get a job until after I give birth due to being high risk. I also have a one year old not from my current boyfriend as well. He helps us so much and is great with my son but I know we moved too fast. I got pregnant by accident a month into our relationship (on birth control) and I don’t believe in abortion (for myself, I believe other women can do what they want with their bodies) I also have BPD and I just completely just lost feelings for my boyfriend. I know I can’t afford a place by myself so we were gonna move in together once the baby was born. But I’m just not happy. I feel like a failure. I’ve known him for about 3 years before we started dating but I’m really unhappy with him. Do I suck it up and just move in with him anyway for my children? Cause I know I definitely can’t afford a place. I can afford myself and my children right now while living with my sister but not a place. Im hoping that when I give birth my feelings come back but I don’t think that’s gonna happen. I don’t know what to do.
