can't stand my brother in law and wife

Maria
Maybe I'm overreacting but I really can't stand them. This might be a bit long. We share an apartment and the lease is under my husband and my brother in laws name. We ended up getting the smaller room and pay more then they do for rent but my brother in law's wife feels so entitled to the whole apartment. The problems started when she started to talk a whole bunch of stuff about me behind my back. I let it go and whenever she needed my help, I helped her. She has an argument with my brother in law and ended up leaving. Then I find out that she continues to talk about me and this time it's my brother in law as well. She came back a few weeks ago and gets mad when I moved 2 of her kids toys from the living room and put it with the rest of the toys. I did this so I could clean. She does not tell me directly but instead texts my husband to "talk to me". And that if I have a problem with her to talk to her directly. But yet whenever she has a problem with me she goes to someone else. I can not stand them. They act all nice to my face and behind my back they talk shit. That's why I decided to just ignore them all together.
