Does he like me or am I over analysing this?

I work with a guy who has more than a little bit flirtatious with me since the moment we started. I have fallen for a player before, and this guy is definitely a player, and I was left completely burned and picking my heart up off of the floor for a long time.

I work with this new guy, and really liked him initially, right up until I realised he treats every girl the same way; flirt, flirt and flirt some more. So I cut my losses and moved on.

Recently I've noticed he pays me more attention than the other girls, and seems a bit odd with his behaviour towards me. I went away for two weeks and he claimed he didn't notice because we 'work different hours', only to comment how much he missed me an hour later. He always comes to me for opinions first, asks me about my personal life, flirts openly with me in front of all of the other girls, and will often intercept my conversations with the other men in my workplace if he sees their behaviour as being 'too forward' (His words, not mine).

He also drops pretty direct hints. During a team building session, where we ended up paired up together, another co worker referred to our pairs as couples and he joked 'Oh, so we're a couple now?'. After we laughed for a bit, he added, very seriously, 'I'd actually be quite happy about that'.

My issue is I'm over analysing every word he says and I'm starting to fall for him again. I don't want to be yet another girl that falls into his perfectly formed line and ends up hurt. Does it sound like he genuinely likes me or do I just need to forget about it and get a move on?

Sorry; it's a long post!
