Most blokes would love the woman to make the first move and most women want the bloke to make the first move.
This causes lots of wires to get crossed and lots of people to fall out for no reason.
Do you know if he's single/married/an axe murderer (ok was joking about the last one!)
Next time you see him, ask him if he'd like to meet up sometime.
Suggest you can do something like cinema or drinks or something, If he's really intersted in you like that you should be able to put him on the spot enough for him not to be able to run away from the situation as with a text message.
Good luck !
