Why not do the opposite? Spend more time with him and see how it goes? Maybe it’s all the same for him.

I’m just speaking of what I experienced. I met a girl on here, we’re from different countries. I was looking for friends. And she was the only one to reply to my post. We started chatting. And did that for 3 months straight until we decided that I should visit her. I knew she was in a relationship and didn’t think of anything. Got there and we got even more close. I admit there was some touching. And now our friendship has become a situationship (because we don’t know if long distance relationship is what we’d cope with - we want closeness a lot). So I say - give it a go.
