I'm not crazy right??

so I have two friends and they're sisters (same dad, different moms) and I've known them since I was two years old. anyway, my one friend has a boyfriend, we all went to school together and her sister and I don't like him for reasons I won't get into, but I know him, I'm too nice of a person to be rude to him, he knows I don't like him but every time I see him I say hi, how are you, I'm cordial to the kid. and that's not enough for people (not just her but other mutual friends and her mom) were expected to treat him like we're all the best of friends, but I've been dating my boyfriend for almost a year now and he's NEVER even met her? I'm supposed to treat her boyfriend who I don't like as if he's one of my friends, yet we have been friends since we were two years old and she never made any sort of effort or showed any sort of interest to meet my boyfriend. there was ONE time when they were in the same place at the same time (we don't hang out as much anymore) and she was in a bad mood so she ignored everyone. my boyfriend has a hard time even remembering her name because he's never actually met her. and the only person who sees this as being unfair is her sister. I don't think I'm crazy for this, it makes total sense that I shouldn't be expected to go above & beyond to befriend her boyfriend when she wont even bother introducing herself to mine right?
