fazz, if I understand you correctly, you were not a dancer until you met this boyfriend and he introduced you to tango. As a result, I don't think you really "get" dancing. All your discussion of it seems to see dancing as a means to some other end--a way to meet people to date or a way to spend time with your boyfriend. Fair enough, since dancing wasn't something you were interested in enough to pursue on your own. But try to understand--for most people who dance, dancing is done to dance--for the pleasure of the activity--not for any other purpose. Many of us don't date in our dance communities--or do so very cautiously--specifically so that dancing will remain enjoyable for itself, without complications from romance. For many dancers, it's just more fun to dance with a variety of people; each partner brings something different to the dance, and that makes for a more interesting dance experience.
