Parents disapprove of my relationship so im going no contact AIO

So i 18F have been in a relationship with my ldr boyfriend for almost 8 months. I am albanian, hes russian/lebanese. At first i didnt tell my parents cause i wanted to get to know him better and tell my parents after he comes visits me. But my mom eavesdropped on me one night on call with him and she totally flipped. She called me a dissapointment, an idiot, a traitor, slapped me and even almost kicked me out. I had a scar from her forcefully taking my phone that night and threatening to break it

For context, my mom sees serbians and russians as the same, even though ive told my mom he doesnt support those politics. She made me breakup with him even though i begged not to cause i loved him, this was around 3 months of being together. So after that i started seeing him behind their backs. Im currently waiting for the opportunity to move out of the country because i feel like if they were to find out again, theyd kick me out. Maybe i shouldnt have pursued this thing with my boyfriend right at the start, but now i have and im in too deep and i dont want to leave him. He treats me like a human unlike my parents. Ive brought this up to my brother and he also looked down on me, he said family needed to be there for each other but what about when i needed them all my life? It doesnt sound really loving when you crumble your child for loving someone else?

Am i overreacting?
