I've had various conversations with him in the past about people I'm seeing etc. He's been away for a while. Suddenly, yesterday he sent me a whatsapp message asking about someone I used to date ages ago, who is not a friend of mine on Facebook. He then sent me pictures of him from Facebook that he had obviously copied saying 'is this him? It obviously is because he has an unusual name' I said this was a strange thing for him to do and he replied 'oh well I can make my own enquiries then'. He has done this sort of thing before and I don't like it - it makes me uncomfortable. So I told him this and now he has blocked me.
I really don't think this is a normal way to behave is it?
