You broke the convo off while it was going well and he was giving full replies to your messages... are you crazy?

Yes what you're doing is futile, I don't believe in playing games at all to be honest when it comes to stuff like this, it just wastes time and if he's anything like me, he'd be more put off if he thought you were messaging 'strategically'

And if you're both playing the 'wait for him to message first' game, then you're both going to lose tbh. If you like him and think there could be something in it, message him and tell him that. Tell him you want to meet for a coffee or something. Just be upfront basically. The worst that will happen is that he'll say no and you'll feel embarrassed, but you'll get over it. The best that will happen is that it could be the start of a great relationship that makes you really happy. Being rejected really isn't that bad anyway, and you'll never get anything you want unless you risk rejection/failure.
Anyway you need to weigh up the two potential negatives... 1 - feeling embarrassed after being rejected... 2 - regretting that you did nothing and never knowing what might have happened. Which one is worse to you? and make your decision based on that.
If you do want the convo to continue though the onus is kinda on you to restart it since you broke it off.
