Newly separated, when will he ask me out?

I started a new job a few months ago. Almost right away a guy in my new job and I fell in lust(?), love(?). Even though I was married, he suggested if I wanted company to go for a day trip again this summer, I should let him know. In the meantime, my husband and I separated. I gave this guy at work my phone # and told him I had time the following weekend if he was still interested (which he said he was) but he already had plans - and yes I believe him.

I know he's fallen for me big time, flirts with me and gives me looks of such hunger (it thrills me) and I flirt with him and think about him night and day.

I finally told him I'm separated a few weeks ago but he hasn't called me. I see him at work often and we talk a lot. I found out yesterday he doesn't have a girlfriend but he does have a friend with benefits. We're both just under 50 years old. He's never been married.

I'm kind of traditional in that yes I have his phone # but I feel that he should be the one pursuing me more actively and yet a very wise girl at work who's known him for years thinks maybe he's waiting for me to call him.

My hairdresser (a guy) thinks men will wait at least 4 - 6 months after a woman separates before they'll take a chance in case they become just the rebound guy. Another guy at work says the interested guy would call her right away.

I'm not looking for committment, just the company of a hot, red blooded male for fun and cuddles until we know whether it's really love or not.
