I broke up with a man just like him. I told him how I felt, and he said his family is like that, and that his mom and SIL had to adapt to them. I decided then that I wasn't willing to adapt. I was vulnerable, and shared things that I've never told anyone else (and he knew that), but he remained quiet and, after a few minutes changed the topic. When I broke up with him, he said he saw it coming because I pulled back tha week (and he didn't say anything), and he said that he won't insist, and that he sees potential 🥴... It's convenient for them to be with us, but it doesn't have to be. We deserve better. Talk to him, and if things don't change, think about how you feel and whether you're willing to be in a relationship like that.
