Is OTHER wrong in the post ? POST : AITA for getting my feelings hurt for something my sick MIL is (or isn’t) doing? 

Some backstory: My BF and I have been living at my MILs house for a couple of months while the house we bought together is being renovated. About a month ago, she was having trouble breathing and went to the hospital. While at the hospital, we visited her and got her anything she needed. One day she said she wanted us to bring her pills that were by her bed to help her sleep. We bring the pills. 

Just to be sure she can take them, we checked with the doctor to make sure these pills won’t interfere with anything she’s already getting.  She was furious. Tried to rip the pills out of my boyfriends hand. Starts yelling and saying all kinds of hurtful things about my boyfriend (that she knows will bother him), that we don’t love her, and when I try to say something she tells me to leave her family alone. We end up leaving the hospital with her yelling even though the doctor told her she was approved to get the same pills but it has to given to her by the hospital. 

Fast forward to when she comes home: She keeps her distance from us. We keep our distance because there was no apology or thank you after we cleaned the whole house from top to bottom so she can come home to a clean, sterile environment.  She’s still not fully recovered or back to her old self and after a while, my boyfriend puts their differences aside and tries to be there for her. I talk to her here and there. 

One thing he’s always done and expected from me as well is kissing his mom on the cheek before we leave the house and when we come back home. I used to do it before but stopped after the whole situation. Since she’s still not back to normal, I try to start doing it again but when I kiss her on the cheek now I get the cold shoulder. She turns her head away from me and doesn’t kiss me back. You ever tried to kiss or hug someone and they obviously didn’t want it? That feeling. 

When my BF does it she kisses him back. It hurts my feelings when my kiss is obviously not wanted and so I stop doing it. It ruins my mood and my boyfriend is upset that I don’t do it anymore, that she’s sick and I should put my feelings aside. Am I the asshole?
