You've never felt that comfortable in groups, preferring instead to be a big fish in a small pond, or even the only fish in your own pond. Of course, that severely diminished the available pool of other fish to partner with, but everything has its cost! Romance is one area where you may have found it beneficial to swim with a larger group, in order to find suitable partners.
Once that happened, you could go back to the smaller social circle, if you pleased.In any event, if there's one thing you prize, it's honesty, and any long-term partners have to have this quality in order for you to feel comfortable. You also have a unique way of expressing your loyalty and affection, something your partners may need to learn to appreciate, and vice versa! You and your ideal partner can make a wonderful, if eccentric, little individualistic group of two, so you can have your cake and eat it too.
