Thanks so much for your help and support! 

An update:  I think the coworker I hooked up with is being a little better, so that's good.  It doesn't feel as tense with him.  Still not sure if I should ask him if everything is ok or if I should just carry on as it has been for now.  Where we work can be pretty crazy and it's hard to find a moment where we could talk without other people being around.

Meanwhile, another coworker- who just so happens to have the same name as the guy I am trying to attract- brought me a bouquet of Valentines balloons yesterday.  He's also been suggesting that we spend time together outside of work.  He's sweet but I really don't have any interest in him as anything other than a friend but I was wondering if the fact that he has the same name as the guy I really want to attract is a good sign?

Like I mentioned before I was kind of holding off on making contact with the guy I want until I was in a better place myself.  (Taking that advice to "work on myself" that everyone suggests.)  I am feeling a lot better about a lot of things in general so I was thinking it might be time to see if I can make things happen with him.  So do I just continue with the RS and hope he contacts me or should I take the initiative and reach out to him?  

I still have some thoughts in the back of my head that we missed our chance etc. so I am not sure if that should stop me.  They aren't the dominant thoughts but they are still there.  The thoughts I had about things getting weird with my coworker weren't dominant either but that still happened so I'm not sure if I should wait.  

Thanks again for being such a wonderful community!
