Really upset... my mom hates my boyfriend

My mom hates my boyfriend and I don’t understand why. I’m 19 turning 20 in a little over a month and me and my boyfriend have been dating for a little over 3 years. He’s sweet, and loving and caring to me and everyone in my family. He helped me through the hardest time of my life and stopped me from wanting to kill myself. He makes me feel special and important and like my l has purpose. He wants all of my dreams to come true and he’s extremely happy being by my side. He’s the best thing to ever happen to me. We’re madly in love. We talk about moving in together, getting married and starting a family. I couldn’t imagine a more perfect person to spend my life with. I truly believe he is a gift from God, no one has ever loved me so unconditionally and wholeheartedly.

But my mother is completely against us, consistently judging his aunt (which is basically his mom) and the way his family chooses to live. Every time I ask her if I could go over his house or if he can come over to my house (I don’t have my own car yet) or say anything about him, she gets angry and yells at me about him and talks about how he’s gonna put me in a situation where I’ll be hurt or he’ll force me to do things I don’t want to. She actually accused him of raping me, it shocked me when she asked but she doesn’t stop until I’m crying. No matter how many times I tell her we haven’t had sex and that i don’t plan to anytime soon she doesn’t believe me. She just ignores me and continues talking trash about my boyfriend.

And every time I talk with my boyfriend about this, he’s nearly in tears, he gets so upset and starts to blame himself as if he did something to make her dislike him. And I hate seeing him so hurt for something that is all in my moms head.

I got a job and wanna save so we can get a place together (He’s been doing the same) but my mom refuses to let me go. She is against me moving in with him. And I would just leave when I have enough money but I literally watched my mom and dad push my older sister into a wall and break through it and so much more to stop here from leaving cause she wanted to move out when she was 18. It got so bad that the cops had to come and separate them and secretly helped my sister leave. I don’t wanna fight my parents. I’m a small girl I barely weigh 100 lbs I can’t fight them off even if I tired.

I love my boyfriend so much and want to be with him for the rest of my life but my mom is making it impossible to do so.

I’m so lost and hurt because of her, I don’t know what to do.
