Helpppppppp

Okay so I had a fling with this boy last summer and we talked for about a month maybe 2 later (we live in different countries) and then we would talk sometimes maybe a picture in snapchat or something and then we stopped talking for like 6 months maybe more and then a few days ago something happened to make us talk (barely) however he left me on read and then today he sent me a picture of the place he was in as if it would be a streak or some. What do I do? Do I ignore? Ignore for a while and answer? Idk
