What does he mean by this?

The guy I’m interested in said that he’s in between a yes and a no about dating me, but that he’s leaning towards a yes.

this is a guy who said he’d only been hot and cold because he knew from the moment we met that I was his mum’s patient (which I didn’t know until later); but that he was interested and agreed with me that he wants us to finish our education first, then decide about a relationship. (My course goes for 6 months, his goes for 12).
