My family doesn’t care so I’m posting here

After meeting my boyfriend and his family, it makes me feel kind of outcasted from mine. My older brother and younger siblings get more attention than me (which is fine, I’m 22 and I take care of myself), but when I need my mom there she isn’t really a mother to me. She expects the worse from me and puts so much expectations on me. My boyfriend’s mom is actually there for me, she listens, makes me feel like my emotions matter, and doesn’t see me as a drama queen whenever I feel like I need to go to the ER/hospital. It’s so new how she treats me that I expect the worse from her and I feel guilty about it, but I only grew up with my mom I was never raised by her. I have a great relationship with my dad, but my mom gets in the way of it. Idk what to do with her anymore. I want a relationship with her, but at the same time why would I wants a relationship with the woman who gave birth to me yet is so toxic towards me?
