Could really use some advice.

It's to the point in the relationship where I'm always the problem. I've been in 4 serious relationships and all ended mutually on both terms & I'm actually still close with them, but this relationship is just.... Wow. His parents hated me from the get go, would even call him to shit talk solely on me (I have 2 kids. He doesnt have any.) And he would have it on speaker so I would directly hear the things his mother was saying, but ofc I couldn't stand up for myself... Even on Christmas DAY, it broke out into a huge fight: his whole family against me. I ended up just leaving. I'm a very, very shielded quiet person. I come from a family of poverty & things that don't matter to most, matter the world to me (I.e: my kids. I don't let go from their touch till they let go of me first.) I'm just drained from always being a problem, even without doing anything. My boyfriend doesn't help at all, and he makes me feel like I rely on him, when I very very much don't. I'm very independent, but its like all of my independence is slowly fading and I don't know how to stop it?? Advice would be great....
