So what WAS his intention exactly? Move through the world self-absorbed and unthinking of other people?
That's "cookie jar sorry" to me. Not at all sorry he was stealing the cookies. Just sorry he got caught with his hand in the jar. Cuz everyone else is supposed to pretend they don't see him.
So I guess now my next move is to figure out what my next move is!
Yup. Having a backbone about your boundaries and not putting up with shenanigans is a good start.
Whether he straightens up and flies right and is worth more of your time -- that's up to you to determine.
But it isn't a horrible thing to be totally ok walking away if he continues to play wonky. You deserve to be treated well.
