What you wrote makes sense.
I do think he respects in a weird way because he flirted like mad, seeked physical contact but never tried to sleep with me.

That other girl is cute and dumb. They have very little in common but she sure isn't threatening.

I do think he has trouble letting me go as an option. Every time a guy showed interest in me he told him to forget it, that I was stalking him.

When I came back from holidays he told me that a lot had happened but he refused to say what. Now I know what.
He thought I wouldn't come back. Lol. Yeah I guess he needed an excuse for running to her the minute I left. In August he thought I was staying at a festival until... when? In March he thought I wouldn't come back from visiting my parents.
Amazing how he finds excuses for being interested in another girl

He seems to have dropped the other girls. Why doesn't he keep them as options?

Maybe he really believes that i am too challenging. In say that I expresd my emotiins but i think i am understanding and yolerant.

When someone is sick or hurt themselves he is horrified and disappears
