I hope I do not make this long.
My sister moved in with me about 15 years ago and lived forv4 and a half years. During that time, she made no contributions towards my mortgage or bills as I encouraged her to save for a deposit for her own place. Unfortunately, she just squandered all the monies she earned on nights out and partying. She's 10byears older than myself actually. One day she got so drunk, insulted me and physically attacked me in my house, calling me cursed that I'd given birth to a disabled child. That was the final straw. Fast forward a few months, she was kicked out of my house and I didn't speak to her for months! I can't remember how I finally started talking to her again. Anyway, over the years, we maintained an amicable relationship until recently, she insulted me during an argument that I have mental health issues.
I am mentally exhausted by dealing with these arguments with her. AIBU to cut off all contact with her for good? Anyone ever done this to a sibling? And how do they feel fast forward a few years?
