Can’t take it anymore

I have lived with my boyfriend for 3 years. (We live in our own place) but his whole family disrespects me. Badly. He never stands up for me. When I ask him to it becomes a huge argument, where he makes me feel bad for ever asking him to? I really love him more than anything, and we have a kid together as well. I just can’t take it any more. How do I handle it? What should I do? Thanks
