Wow, I'm impressed with your system.
I've been on indefinite hiatus from dating, in large part because a relationship feels like too much work to me right now. I enjoy not having to please anyone but myself, and maybe I'm just too damn selfish. On the positive side, I'm not making some poor guy miserable. :-)
My biggest problem has always been worrying about hurting people's feelings (no matter how much of a jerk they are), and also getting swept away by people who simply like me.
I have a feeling that the emotional wall I have around me isn't a hundred percent healthy, either, but right now it feels safe to me. And I'm not unhappy or lonely, so maybe that "should" thinking is just me imposing other people's values on myself.
At some point that may change, and I may be ready to open up to the possibility of sharing my life with someone else, but I don't feel any particular need to rush it.
