help me please i need some advice?

so i have a boyfriend of 3yrs and we are long distance.i love him so much and he says he loves me too.we been arguing about little stuff.i have given him so many chances that ppl might think im crazy.he is asian so i kind of feel like his mom is finding ways to break us up.for example she told the neighbor to not talk to me no more or they wont be friends.another example is she was saying some stereotype about me bc im black.so that's one of my problem.another problem i have is my bf blames things on me and like yell at me for no reason.it drives me crazy.i have told him not to do it and it last for like 2weeks max.he acts as if i cant do anything.one time he said some racial comment.there so much things i can say but my question is what do i do.Should i end it or should i stay?am i being over dramatic or i am doing it prefectly fine?what can i do to better our relationship?
