Is he into me or playing?

[hoolababe]

I've known this guy through work for a few years. Since January we've started going round in the same group. We flirted for a fewmonthe, had a minor misunderstanding,he was very nervous around me for a couple of weeks after. Now a few weeks on from that I sent him a message telling him that a video I just watched made me think of him. He replied with a smiley face and was looking at me nearly all the time when I saw him next. He came into work out of the blue yesterday and I couln't stop smiling and my heart missed a beat. He blushed and said he would see me at work again on Friday and seemed crest fallen when I said I had a week off. Do you think he's into me as I definitely am him! We're both wary and bit shy round ech other.
