So mean and very ugly!!!! he looks like the hunchback of NotreDame.?

I needed help with my job application, so I was like to my bf's sister's husband "oh do you mind helping me with this job application" i was all nice and everything. His response was "the only person I help with homework and stuff like that is my wife." i was all shocked and embarred, could not believe he said that to me in front of everybody. my bf's sister ran away and marry that guy abt 3 years ago. when i fisr started dating my bf, he used to tell me how he hates him and he doesn't know what his sister see in him cuz he' so ugly and rude. I was the one who was always telling my bf to stop being so mean and give him a chance in the family. so abt 2 months ago the family finally accepted him, so they've asked them to move into the house. i was all trying to be friendly with him, making sure he's comfortable and that was how repaid me by acting like a complete brute. my bf was like "i told you he was a brute, but you didn't believe me." now i cant stand him.
