Who knows? If you're waiting for him to ask you out .. Why don't you ask him out first? What are your excuses for waiting?
why does a man always have excuses when its time to take a woman out?
He is either too cheap and broke and dont want to tell you OR
He is married, in a relationship or taken and dont want to tell you OR
He is extremely shy and putting up a fake front on line/ over the phone.......
Either way I would stay clear of him. Sorry.
