Feelin' the spurs

Not sure you'll recall, but leading up to my 30th birthday I decided to make some bold moves. Unfortunately, months later I am now left questioning my judgement in such a strategic decision. NotCowboy was the 40-something heartthrob I lusted after for months. We had clicked early on through our work on a mutual work project. So...upon realizing I was about to enter what I officially considered real "adulthood", I called and left a message on his machine explaining I enjoyed his company and was interested in getting to know him better outside of a work environment. I was really interested in jumping his bones, but tact, at least, kept me from saying that. I never heard back from him and pretty much let it roll right off my back. After all, it was only lust and the work project we shared was wrapping up. So, why bring this up now? I found out a little over a week ago that there was a big media event for the project we had partnered with his company on. Normally, this is the kind of event we would have helped plan and would definitely have been there. However, did I even know about it? Did he call me or email to ensure I was in the loop? Hell, no. Is this something he would have normally done pre-friendly message? Hell, yes. It now appears that my decision to be forthcoming about my feelings will effect my position on a work project. Sigh. Sad to learn even older men still retain the immature gene.
