Wondering my my 31 yr old SO is always so mean to me whenever he has his daughter... every time she’s over he’s very cold to me and calls me annoying and tells me “fuck you”

Most recent example he tells me he’s gonna buy her some timberland boots.. I ask why buy a two yr old timbs, she’d be happy with snow boots w a character on them plus he doesn’t allow her to play outside she’s never outside more that 2 min at a time and when she is he’s carrying her. He freaks out and is calling me annoying and not to worry about it, telling me fuck you bitch. And his daughter acts the same way to me..
