I just need my family again even though they hurt me

I left my family and hometown about eight months ago to live with my boyfriend and his family in a town more than hour away. There’s a lot of backstory but the ultimate reason to why I left is because my moms boyfriend hates me and was verbally and emotionally abusive towards me and often kicked me out to live with my brother. The last time he did, I refused to move back in and my boyfriend’s wonderful family took me in, clothed me, fed me and pays every month for me to attend online school so I can graduate on time. I couldn’t be more grateful for them and everyday they show me what a functional family is supposed to be like. Since I moved it’s like my entire biological family has disowned me. My brothers don’t call or see me and my mom acts as if my boyfriend and his mom are villains that took me away and are holding me hostage. She refuses to accept that she allowed her boyfriend to push me away and abuse me in front of her. The stress and emotional pain I endure everyday from missing my family is breaking me. My nephew doesn’t recognize me anymore and I’m missing out on so much. I know they’re toxic and I shouldn’t miss them or want their approval but all I want in the world is to be held by my mom again and take care of her like I used to. I know it would only hurt me more, but even after all of the abuse and trauma she’s caused me all I want is for her and my brothers to hold me and be proud of who I’m becoming as a person. I miss them so much
