I met a man from online, basically for casual sex, but I ended up liking him more than I thought I would. He said he was going out of town, but I have seen him online and sent him some messages. I was asking him why he wasn't saying hi or anything. So he says not to smother him. I sent him another email that said I was sorry. What do you think I should do? Should I try to email him again or leave him alone. I feel like I messed up and even though it was casual he said in the beginning he wanted to do this more than once...how could I get his attention again?
