Married coworker switches between flirting and ignoring me?

Anonymous

He's older then me and married. We get along well: we work well together, we think in a similar way, we've got a similar sense of humor.

I am nearly 100% sure he has been flirting with me the past months: he lighlty played footsie with me a couple of times, he pressed his knee on mine while sitting next to each other (in both cases, I did not move away), he calls me to tell me stuff even if not necessary.

Then, after clearly (?) flirting he switches to completely ignore me.

I like him. I've been looking at him in a discreet from day 1 and I think he knows.

Some info about his personality: he in general switches from being very nice and fun to being very cold. He's got a strong personality and can be hard sometimes, but I'd also say he can be very sensitive underneath the surface. I really have a gut feeling that he likes me. There's other men at work being kind and asking about me, but I've never felt like any of them was flirting. What do you guys think about It? Why is he behaving this way?

thanks
