Family

I really can’t stand my daughters dads family. I blocked all there numbers . There extremely disrespectful and I’m quiet. I really want no parts of them. Am I wrong. Him and I aren’t together I told him the fact that he allows his family to say certain things is very rude and makes me uncomfortable. I feel like they want me to become irate with them. I’m totallly fine with me daughters dad dating . I recently brought our 4 year old to a party for his family. The girl he cheated on me was there because his family invited her , he did not. I avoided her at all cost because I felt uncomfortable. His sister kept making unnecessary comments and it caused an argument in which he stayed quiet.
