Look, I know she's being ridiculous and you are just trying to help. However, in the interest of you not being evicted, I'm going to propose another day to look at this. Is it possible she doesn't understand why it would cost less, and she feels like she's being forced into something she doesn't understand and therefore doesn't trust? I know she should trust your experience, and it's super frustrating and disrespectful that she doesn't. But maybe because you do know more than her, she feels like you're being a little pushy instead of hearing her concerns. Again, she's being ridiculous and you are right to be angry. But you have a long history with this person and you maybe don't want to have to scramble to find another place to live. Maybe you can hear her out and work through this.
