Cute guy at work, how can I get the ball rolling?

There's a guy at work who I quite like, and I told him. The only problem is, he smokes. I don't.
So I said to him "You know, if you didn't smoke, I'd probably really fancy you."
He replied, "If you smoked, I'd probably fancy you too."

The day after, he said he felt gutted because his internet was down therefore he couldn't add me, and it's now been a few more days since then and he still hasn't added me!
Do you think he's interested in me?

I don't want to bug him. Any ideas on what to do now?

lol why did you say that, of course he didn't add you. you should have flirted with him not say that!

anyway its never a good idea to get involved with people in work

Start smoking.

If he's interested in you he'll contact you.

And smoking is a bad habit, my girlfriend smokes and I've told her how much it bugs me, I think she's going to quit...

At least that's what she's said, lol.
