What do you all think about this......

I work with someone who, for many months, has said to other colleagues (who then somewhat indiscreetly told me) that he likes me A LOT. He apparently thought I was very attractive, clever, good personality etc(all of this is of course entirely true )

When I first heard this I wasnt overly interested for various reasons - mainly because he seemed very quiet & reserved, not in any way my usual 'type' - in fact the total opposite. Anyway, spoke to him at a few work functions & got to realise once he relaxed a bit out of work he was really witty & good fun to be around. And that we also had a surprising amount in common.

At the last function, we both got quite tipsy & after it finished ended up snogging etc

I was quite matter of fact about it afterwards, & asked if he wanted to just leave it as a one off, or not - and he said definitely not.

So far, so good I thought.

Then 3 days later, when we're back at work, he says hes scared of getting into a relationship (I'm not sure I'd offered one, I just thought we might go for a few dates at first) So I said fine, we would see how it went. He said ok.

That was about 6/7 weeks ago.

Since then, we chat at work, and exchange numerous emails every day. I invited him to a drinks evening a few weeks ago with colleagues, or for us 2 to go for a quick drink which he declined as he already had plans - which he then told me about in great detail, making it clear he was either with his DC (he's a single parent like me) or with other (male) friends, or clubs etc he belongs to. He said he would come some other time, but didnt suggest a date (mind you, I havent since either)

So, I've been reliably informed he likes me. I think I've made it fairly clear I like him.
Despite that, we now seem to be just friends. Am I missing something? Or wasting my time?
