<human>: Can you succinctly summarize the text in 1-3 sentences?

It is honestly annoying. To be fair my mother has treated me like crap for most of my life. Not going to go into too much detail but I don't have the best mother in the world. I think a lot of females that I have seriously dealt with notices that and they try stand up for me when she does something cruddy. As much as I tell them not to they can never just ignore it and then boom, my mother and my girl are mortal enemies just because she spoke her mind. 

My current girlfriend tried to do the same recently and now my mother swears up and down that she's bad for me,she's the devil, blah blah blah and that she's cutting me off until I can stop being brainwashed. I just hate how every time I get involved with someone it always ends up with my family cutting me off because my mother feels some type of way. To be honest my family treats me like crap, but I try to maintain the little relationship with them that I have. Just like the others, I tried to convince my girlfriend not to worry about meeting my mom or my family because I know how it will end, and just like I thought the same crap. My mother doesn't like anyone sharing their opinion about something they don't agree with because the moment they do she lashes out like a child and then words get shot back and forth and then this happens.

I just don't know what the right thing to do is anymore. I feel bad for cutting off my mother even when I know she's wrong, but I feel like I'll never be happy with anyone as long as she constantly tries to interfere with her shenanigans. I just don't know what to do. I haven't spoken to my mother in a week and I feel bad even knowing she's wrong.
<bot>: My mother is constantly destroying my relationships and I don't know if I'm doing the right thing my distancing myself.
