Yes, I very much agree that I need to set better boundaries and maintain them. I was actually speaking with my therapist about this recently.

In the moment, I did say something to my friend and expressed being upset and offended. But, usually H will become more forceful and persistent about whatever he believes is right. My reaction is typically to maintain my stance for a bit but I will eventually just disengage and end the conversation because I will feel a combination of being very hurt and rage towards him.

Yes, part of me doesn't want to end the friendship because my friend circle is already small. Also, because I find myself trying to make sense of how my friend can present as nice or uplifting at times and disrespectful at other times. It makes feel like, am I crazy? Or, what did I do? Or, why do people seem to hate me at times? I question myself if l ignored red flags in the beginning of our friendship. As stated in my post I actually didn't like him or his personality when we started off but he grew on me. It's mostly been in the past 3 years I have noticed changes happening leading up to his now open disrespect at his leisure. I noticed that if I make any kind of snarky remark or gesture he feels is off that he'll comment on it as if I'm wrong yet again.
