I have posted before about this and got some good advice, just want another rant/some advice I hope.
I separated from H last year and really fell for another guy in work at this time, and I sort of came onto him
flirting, eye contact etc etc. He was up for it and give this back some days and then at other times, he was cool and aloof with me. To be honest we've been dancing around each other like this since last summer, playing games. I was getting obsessed on him and that's not healthy I know. Its been incredibly thrilling, but also downright adolescent. Doesn't help that I haven't have sex since splitting from H last year so deeply frustrated too 
Anyway I have been trying to give up the idea, ignore him, only to have him go out of his way to pay me attention. I'm still so attracted to him, but I really think he is playing me as he must know how I feel about him. God I feel about 12!!
I'm not leaving work as I need and love my job. I'm now so annoyed because I started this stupid thing and it won't go away. I would still have him though if it was on offer 
A work colleague told me he was married, probably explains his behaviour, but there's no other evidence to this, i.e. wears no ring, nothing on his fb etc etc.
Any ideas how do I get over this obsession?
