After 2 months of being together my coworker and I called it quits -- rather he did, and it sucks. Now I don't know how to act when I'm around him anymore. We spent 2.5 years flirting with each other, and now it's like I don't know how to "not flirt" with him. So I've resorted to the cold shoulder -- and here's the thing, he's acting hella friendly with me, trying to start conversations with me, compliments, etc. But I want nothing to do with him right now -- kinda still tending to a broken heart.
