Inlaw problems!

So ever since the beginning of mine and my SO relationship my inlaws have never been welcoming. We been together for 3 years now have a newborn. I try to be extremely nice around them but every time i supposivly do something wrong and they say i dont like them or want to be around them to my SO. Idk what else to do. I dont like to go around them now because i feel im a bother and everything i do is wrong to them. They talk behind my back. Its not right. Every time a holiday is coming up me and my SO get into it because i dont want to go over because i feel unwanted there. Idk what to do help me ladies!
