AITAH for kicking my sister out of my house and cutting ties with her
So I (28 yo M) live my for gf (26 yo F) and my mom and younger sister (23). We’ve all been living here for about 5 years but I kicked my sister out today. Over the years she has had issues with my girlfriend. One incident is when she kicked our door down after she overheard her complaining being dirty and attracting roaches into our home.(which is true). Last week was the last straw. We had a 7 year old Yorkie who we loved dearly but last Saturday night she left the door open when she came in and the dog ran out and got run over and died. I’ve told her multiple times to close the door. Once I came home and it was wide open with nobody home. I have cameras for outside so I knew it was her. It wasn’t the first second or third time she’s done this. I have her a week and today she left. I told my mom that I disowned my sister starting today and it did make me sad seeing my mom cry but I’m firm on my decision. My sister has no remorse for her actions and she never apologized for our dogs death. She said “whatever” when I confronted her. I’m done with her.
