How do you deal w in laws not liking you (2yr relationship)

I get bad looks from them when I’m around & they don’t acknowledge me. My bf told me they’ve insisted for him to basically cheat on me before, but he shut it down. The only time they like me is when It’s in their benefit. One time his mom had him ask me to borrow $2,500 & I didn’t hesitate as much, since I knew it was for their home. She ended up only paying me half and only telling my boyfriend the rest of the responsibility was his. Another time his dad had him ask me to get an atv in my name since they know my credit is up there. Then, the teen sister got a bf for a short time & wanted us to all go out long distance without helping pay for my cars gas. Other times she just mean mugs and sometimes makes shady comments, especially one time when my bf’s ex was around just to impress her. (They’re 2yrs apart & vape together ofc I’m not in the category)

But after all, I don’t really speak to them. I barely go visit anymore and the dad has asked me “why”.

Is there someone in a similar situation or can give advice on how I should respond to the situation.? Thank you

Ps. His parents aren’t even in a happy / loving relationship, I only hear about them having drama within.
