I met this guy in the Summer and we flirted a lot because we saw each other everyday. We went on a date and I stayed at his, although nothing happened except sharing a bed because I didn't want to do anything on a first date. Anyway, whilst I was away in August he moved away and we've still been talking. A lot of the time it was me initiating conversation, although it's been more two way recently. We flirt with each other a lot and he keeps saying he'll come up and visit. However, during this time I found out through social media that he's been engaged the whole time I knew him. This upset me but I still want to see him. I've been sending him a lot of pictures recently which I know he likes. I then asked him to turn me on by talking dirty to me (cringe) but he didn't reply. I sent another message and he still didn't. I have no idea how to approach a new conversation with him now because most of our conversations don't begin with a simple greeting. Does it sound like he's actually interested? What should I say to him?
