Please forgive the schoolgirl title, I'm so out of practice with this sort of thing and am working myself into a gibbering wreck. I need some clear-headed advice!
There's a guy I really like at work, I think he likes me too but I can't quite bring myself to believe it - he's younger than me, great personality and bloody gorgeous.
We've known each other a while and have always got on well, but have recently started to spend lunch breaks together quite a lot and have been out after work for drinks a few times, sometimes with a group of colleagues but mainly just the two of us.
He's so lovely with me, he opens doors, buys me drinks (I do reciprocate when he lets me, obviously!), hand on my back when trying to get through a crowded pub, little brief touches etc. But then I think maybe he's just a real gent and I'm reading too much into these things.
We've always had a bit of a flirty banter thing but it's changed somehow, he's quite a confident personality generally but lately he seems shy and a bit awkward around me sometimes.
Anyway, on Friday we went for a quick drink after work and I mentioned I'd be away next week so wouldn't be about - the next thing he's picked up my phone, saved his number for me and called himself.
So now we have each others numbers but I'm too bloody scared to text him without a reason 
So does any of this sound promising at all or is it all easily explained away as just friends?
