My friend hates my boyfriend. Should I try to make her change her mind?

When I told my friend about my boyfriend, she said “why are you doing this to me?” and started telling me that he is “ewww”. If I like him, what’s the problem? I mean, he’s my boyfriend and I think it’s weird that my friend keeps asking me to break up with him. Yesterday she wrote our names and then the word “bullshit”. Okay, I know he’s not her type (and he’s not even supposed to be her type anyway) and that he’s not my type either, but I like him ‘cause… um… I don’t know why but I do. Anyway the question is should I try to make her change her mind or should I let her tell me the reason why she is so negative and maybe let her make me change my mind?
