I regret buying a house with my boyfriend. What should I do now?

I'm on the fence about my boyfriend after we bought a house together. I did most of the work to secure the mortgage, paid 90% of the down payment and closing costs, and handle the renovations, including dealing with mold, which made me sick. My mom and sister live with us, and I offered him less than 50% ownership since they take up more space, but he wanted 50%. After we moved in, he regretted the purchase, saying there's not enough space for him. He then claimed his friends thought he was being taken advantage of, though he later admitted they didn't say that. His lack of support and doubts about my efforts have created serious trust issues. Now, I'm considering buying him out and redoing the mortgage, but I'm unsure if I can trust him or move forward. What should I do?
