He knows or thinks that you've moved on from him. So he wants to know he can get you back. Once you fall for that again, he will revert to "not sure what he wants", "not in the right place for a relationship" blah, blah, etc.

when he sees me drifting off he makes a small effort to rein me back in again but would never normally have risked me taking dd somewhere where she scould see him in front of our colleagues. Which was just bizarre.
Also implied he would drink which would have meant me giving him a lift home (or rather back to my place)
