I recently had an altercation with a sister who said some very awful things to me. One of the things she said was that she nor my other siblings have ever, ever felt comfortable at my place because I don't make them feel "comfortable." This bothers me because a few days before she said this (and other things) to me, she was "comfortable" enough to ask me to open a phone line on my account for her so that she could get a discount. Not only was I willing to do this for her but I also had to call my phone carrier for about 2-3 days straight, since whatever she did didn't allow the transaction to completely go through, and I did this all in between work, driving, chores, and at my daughter's baseball games while watching/chasing my toddler around. This is upsetting to me. She isn't talking to me anymore and what she said came out of no where. What I want to do is close that line off but I'm afraid it'll backfire on me (she'll use it against me). What should I do?
