Most Helpful Guy
Well he still likes you. Highly inappropriate behavior not just because he has another partner but obviously also because you don't want contact with him. Or have you not told him so? If not then you need to tell him to back off.0

This is the best question, nicely worded, 10/10 did appreciate.
Did you guys end on bad terms, good terms, no terms at all? Because hey may thing you guys are ok with one another and that's why he's doing friendly-ish things to you.
OR he is telling you that he's happy with another girl to make you jealous and to show you that he's 'moved on' even if he hasn't.0
