Is he playing me??

So since I was about 12 (I'm 17 now) there was this guy at school that I really fancied. Like so bad. I had a few boyfriends but I was always really attracted to him and there was something about him that made me always like him.

We used to be friends but as we've grown up we grew apart until now. He's extreemly popular and "cool" and I'm not really which is why we grew apart.

We always kept in touch even if no one knew that we were still friends. I either felt like a mug because he was just using me to talk to when he had no one else and that's why he didn't really tell people we were friends or I felt special, like his little secret because again it was funny that all these girls would want his attention, and he was giving it to me. Since we've left and finished school we started talking again. I do think he is very attractive and I always find myself flirting with him. It's like he gets in my head and whenever I'm talking to him or with him I just do and say things I probably wouldn't normally. 

He is known for being a bit of a player and he has a lot of friends that are girls. At first I thought I was just another one but now I don't know. I know a few of his girl mates and from talking to them he doesn't seem to be the same with them as he is me?

There's one problem. I have a boyfriend. I've been with him for 2 years and I am extreemly happy with him. I love him more than anything and he treats me like an absolute princess, I couldn't imagine my life without him. However, I still get these feelings for this other guy.

When I look at the situation I would clearly be stupid to risk my relationship for this player of a guy. But something is telling me that maybe he isn't playing me? A few of my friends have even started to notice that he gives me a lot of attention and they really think he likes me. He's asked to meet up with me a few times, just to see me and I'm actually terrified because I don't want to do anything stupid. 

I guess I'm just curious, after liking this guy for so long and now he's finally giving me attention I guess I'm just curious to see what would happen. I definatly wouldn't break up with my boyfriend for him but I wouldn't mind kissing him I guess. I know how aweful that sounds!! I'm just so torn right now because I really love my boyfriend and I don't think it's worth loosing my relationship but agh someone please help!!

What if he doesn't want a relationship and he's thinking the same?

UPDATE: since this post I've tried meeting up with him twice just as friends because that's what we are and we haven't seen each other for about 6 months as I study away mon-fri and both times he's bailed. First was because he felt ill and forget to tell me he wasn't coming out and second time he said he was free but actually he was still at work so I couldn't meet him. The first time he seemed really apologetic and I thought he genially meant it but since the second time he hasn't spoken to me. It's only been a few days but I'm just confused. He was so keen to meet up so what's changed his mind. I don't think I want anything to do with him now because I've definatly been mugged off. 

UPDATE#2:

I spoke to my boyfriend and explained that I want a break so I can mingle and live while I'm young and not have such a serious relationship whilst I'm so young. Is that so bad? Because he's not getting it and it's extreemly frustrating when I've only ever been honest with him and told him everything.
