Mother-in-law Hell

Well its been a few years that I had to take my MIL and SIL crap. They have been rude, ugly, and ignored me purposely when I would still try to have a conversation with them. I wanted for them to treat me how anyone would want to be treated. Since I got married and had my baby its been a battle. I am a stay at home mom, I have tried to work at jobs but it really didn’t pay off with small checks coming in. I take care of my children, stay home, do everything a good Mom and wife are suppose to do. I get NO credit from my husbands family. My MIL helps my SIL but has told me I need to get someone else to help take care of my child when I go to work or school. But she has the other child all the time. My MIL is helping my SiL raise her child. I ask for no help b/c I am glad to take care of my child. The only thing I could think of is that they don’t approve b/c I have no money and I don’t come form money. I HAVE NO IDEA, WHY THEY ARE SUCH SNOBS. Apparently after all this time I am not good enough. But I was good enough at one time to babysit my sil child. Once I said I wanted to go back to school again she stiffs her nose in the air and I am dirt to them again. I have not been giving even a little effort in trying to make some kind of a relationship with either of my in laws. I am actually not even saying hello anymore. I feel lots of hate and disgust on how fake they are. One day they say a few things and act as if there are no issues and the next day it back to “I am better than you”… I am about to blow up and go all out saying what I really think. I do hope they are starting to get an idea that I am tired of their shit. Sorry about the language. it is causing trouble between my husband and I. I don’t want him to choose sides but, I can no longer be a puppet around his family and act as if there is nothing wrong!!!! WHAT TO DO??
