I need help... mother, daughter, boyfriend

I have had a very toxic relationship with my dismissive mother my whole life. A dismissive mother is someone who will never give you congrats or validation when you need it the most and will ignore you when you are literally right by them trying to talk to them. A few years back I had been depressed and over weight for over a year and asked her for help (therapist etc.) and she ignored me. By better yet would yell in my face and tell me “that doesn’t look good on you.” Or “do you think you even look good?” I was at a point where I though “if my mom who gave birth to me, doesn’t love me. Who will?” My mother has been mentally abusive my whole life. But I have gotten over my depression but I still have her voice in my head saying I will never be good enough. And now that I am in this beautiful loving relationship with my boyfriend. I feel enough. Not because of my boyfriend but over the years of not living home I have found a sense of self worth, love, and care for myself. From moving away I have seen a positive improvement. But now since my boyfriend lives back in our hometown. She is trying to come in and tear us apart. She spits lies at me to scare me. Like “you love him more than he loves you.” And she even lied saying she saw him flirting with someone when in actuality it was a huge lie and she couldn’t even come up with “who” he was flirting with.

Butt now it’s gotten worse. She is starting to ignore him too when he tries and tries to talk to her and get to know her. He is such a strong man who wants to get to know my family. But my mother is making it so hard.

I am 22 years old and a college graduate who all of a sudden is STILL being controlled by my mother. Has anyone gone through this? What should I do?

I love her but, I love him and want a future with him. I just wish she would open her mind and let him in. I just feel that since my mother and I have had this toxic relationship that what she’s saying is because she thinks I’m a fuck up (which I’m not)
