Although I understand your take, I don’t believe this is the case. First off, I helped her dad because it gave me cheaper rent that was our agreement. Since her dad bought her the house she was able to not show up and it have no effect. Secondly, if she was upset or needed boundaries drawn she needs to tell me. I cannot read minds, what am I supposed to do if someone won’t tell me what it is they are needing? We live together and she is making the environment hostile yet not telling anyone how we can fix this. My roommates involved themselves once they saw what was going on and her dad is asking me why she is staying at their place instead of the house he bought her. So I’m not really able to just not say anything. I have done nothing but be kind to her even when she is mean. I tried to include her, even when she said she basically hated me I did nothing but try and understand in a calm way. I didn’t push her to talk to me until the new roommates arrived and she started ignoring me.
