There is a guy in my friendship group who I see him once a month when we all go out. Lately every time I see him the first thing he asks is how the dating is going. I try to change the subject but he says we can talk about 'life' later. He asks if I have been on dates, how often do I get asked out and when did I last have a boyfriend. He smiles when he asks these questions. Is he interested in me or just nosy?
