Understanding an aquarius

So this Is my aquarius dilemma. Met this guy a while ago at work, always had a bit of banter but never done much about it because 1. He had a gf and 2. He's way out of my league anyway we started talking loads and told me he and his girlfriend had split about 3 weeks ago, he said they never really had a lot in common he started messaging me on fb and always contacts me first and coming and finding me at work he's been quite flirty. I really like him but understand that he's just got out of a relationship so isn't looking for anything serious I just wanted to know for other aquas what might be going on with him, is he looking for a quicky or some fun? Thanks

OP, Aquarius is supposed to be very committed to a partner although he doesnt show it on the face. I dont think he's that quick to forget, most likely flirting to have some fun. You shouldnt take him seriously. If he has really forgotton his partner so fast, dont think he's a good catch either although aquarius is logical people but he should at least choose his next partner wisely. Just have fun with that dude but dont take it seriously.

or maybe just friendship or an option.

If you like being an option then hey why not.

First of all, there's no such thing as "out of my league". Every human uses the toilet . Keep that in mind
That being said, I can only guess , he was tired of his girl anyway & he had been interested in getting to know you since the beginning OR
he might just like you as a friend & feels like hell find some sort of support in you.
Either way, dont the say that aquas like to start off as friends anyway?

I don't think its wise to say that he is serious about a relationship with you, just because he flirts.

During my high school, I used to talk to a lot of girls too. Some thought I was flirting with girls. But it was far from the truth. Aquarians by nature like to be nice to everyone. Maybe he is just being nice to you?

I think you need to put the microscope away and focus on how great life is.

Well, I'm Aqua male and there is no such thing as a rebound to me.
Moving on is moving on. Trying to go back is going back. Keeping things friendly is just that. I've never needed to go get laid just to get over the last. Too emotionally clingy sounding if you ask me.
But there are too many possibilities in the situation you described, but if you are questioning it, sounds like there is more hope/intentions on your side of things.
Just be up front and ask or drop subtle hints as to your boundaries just in case. But also, as febaqua says, I've just attempted to make new friends before and it's been taken as flirting as well. If his old relationship was someone dragging him under the water constantly, finally being able to mingle and be happy may be liberating at the time being.
Maybe he dealt with an emotional abuser type who judged and fought his take on relationships and things got ugly because he didn't change forceably.
Of course you know best as you are in the situation. Just some extra thoughts.
Question is, do you hope he is flirting? If so, do you hope to just have a fling, friend or a relationship?
