@VanGoghsDog interesting point, and yes - we worry about that too. One one hand, we're meant to lead the way, however on the other hand, we're told to play it cool and that if you're too available you're no longer attractive. Hence I suppose why there are all these daft rules about not replying for x hours/days.
Personally, I hate all these games, but I have been told a couple of times that I'm rather keen. But I suppose these games do work though, as if someone (woman or guy) is slow to respond, the other person becomes anxious waiting, and feels joy or relief when they hear back. My view though is that if you need to play these games, it's not going to work.
Saying that, I have friends who sometimes take days to reply to messages so I appreciate that not everyone has the same communication style as me.
If someone likes you, then things are just easy and you don't even think about it. You don't need to worry about being seen as keen if you reply after 1 minute, and you don't need to worry about being seen as distant if you can't reply for 12 hours. You just know if someone is interested in you - by the things they say, as well as how quickly they reply. Similar to @bangheadhere40 I've found if I have to question whether they are interested - it usually means they aren't.
As for wanting to meet after a date - I've been on dates where I've just felt there's been no chemistry either way, so quite often those ended in mutual ghosting. I've also been on dates where I thought we got on well, both said we'd like to meet up - then when I've sent a follow up message to arrange a second date they just been ignored. So now, if I don't feel a spark I'll send a short "lovely to meet, but no spark" type message. If I like someone, I'll tell them at the end of the date that I've had a good time, would like to meet up again but will leave it for them to let me know if they feel the same - so there's no pressure to turn me down to my face 
@Newuser991 I agree with the other posters who think he's looking for a casual fling.
