Do you feel strong enough to deal with this guy without you feeling dragged by deeper feelings?
I think this is a thing to consider since you already noticed, by knowing him, that there are things you won’t ever take in well and that he doesn’t want a serious relationship as a couple.

P.S.: You’ve already learnt a lot from this relation and about you. Maybe, he’s a a stone where laying on in the middle of the river to cross it and find the right person.
