Hey everyone, hope you don't mind me joining in - I used to post in the dating threads about a year ago, but have still been reading. I gave up on OLD but suddenly have a RL interest to discuss 
Bloody when I was doing OLD I would only message after a date to say I didn't feel a connection if they messaged me after the date first. They always did so I did always send the message instead of ignoring. I had to block one though because he just would not let up (was my first online date actually)
Ok...so currently I am interested in a guy from work. He's a few years younger than me and works in a different department. I have only chatted with him in person on about 3 occasions over a period of 5 months (our paths don't often cross at work). Anyway, I found him on FB and sent a wave, which resulted in him sending a friend request and now we are chatting (I don't know if he's single, his profile/pics don't indicate and he doesn't seem to use it much...but I feel as though he might be interested). I don't want to play games, but don't want to seem eager, I have already initiated this. Is it best to mirror the response times? He doesn't seem to be online much if the messenger last active is accurate. I.e. yesterday morning we exchanged a few messages but my message was the last one in the morning and didn't hear anything until afternoon the next day. Thinking my response should at least wait a few hours. I haven't clicked on his message yet so he'll see I haven't yet read it. How do others handle it?
