As I mentioned in the other thread, having a single person that I'm close to has been a really good opportunity for personal growth for me. It hasn't just been an opportunity to explore my capacity for devotion to others, but I've had a chance to work on my anger, to work on conflict resolution, and all sorts of other things that have helped me achieve greater peace in other areas of my life. I can see how it would be a problem, if people decide they only need to apply these things to their partner. However, loving at least one other person deeply and making a commitment to them has given me empathy for others that I had trouble with before. Probably a good thing.
