Husbands family

They are honestly very two faced and judgmental. My husband and I always do stuff for them and it's just never appreciated. It drives me insane. My husband helps do stuff at his moms house and even gave her $100 towards her water bill a few weeks ago cause she had no money. We babysit my brother in laws kids ALOT! I don't come from a family that is two faced and negative. My mother in law talks shit on everyone and is always negative😡 she honestly doesn't care about other people and in the last 7 years I don't think she has ever asked how I am doing. anyone else have to deal with this? How do you handle it? We don't have kids yet and I feel like it will irritate me more when we do
