Update: He has not come up to my apartment again so far. He does try to be friendly with me in the hallway when he sees me out there. I am pretty disgusted by this person now and I am short and brief. When he says "how are you?" I say good and my tone shows I don't want to talk or engage. He leaves me alone, but it's clear that he still wants to engage. I do not want this anymore. But I do feel guilty. I feel like a really big jerk. I do feel ruthless, because I had been so nice and friendly with him before. I feel like I've done a 180. But I'm not going to change. I'm pretty disgusted with the fact that he's looked me up and down on multiple (every) occasion when I had been friendly with him. I hope it's ok that I have changed my tone / tune. Is it ok? I can't help that I feel disgusted.


The other thing I noticed, is that I sort of let my feelings of disgust and annoyance and anger towards this individual "ruin" parts of my day, after having to briefly interact. This is something I'd like to work on: self care, and cultivating positive feelings, letting it go - while also continuing to be short and brief (and unfriendly). I will check my DBT folder for some help.
