To tell the truth, I like the singleness, and the ability to do what I want without interference. However, when in life can I do a lot of that? I do my artwork, and really would not mind someone doing the dishes in another room. I grew up in a household of 6 kids, on, and sometimes 2 parents. At one point, 14 people were living in my house. I'm actually used to lots of people, but I tuck myself into my own little world. Right now I have 2 cats, 2 dogs. They kind of make up for the people.
I am going into a line of work now that pays well, IF I Can get out of town on long distance trips. Now more than ever, I want a significant other to take care of my things and animals when I am out of town. I live with a friend, an old guy who has cancer. He is a bummer, and will not do anything for me. I understand he is weak, so I don't ask him.
I also get very stuck in ruts. I do like travel, but getting me out the door is hard. It takes a very hard push to get me to go anywhere. I need someone to push me. My things are long walks (nature walks where I classify plants, and pick up specimens, usually), museums, aquariums and so on. So I do like to "get out of the house." I prefer to be alone, but being with a friend is nice.
Finding someone who is tolerant of my oddities would be very hard. I have an unmarried opposite sex friend now who is occasionally going out with me, but I don't think it will be serious. It never is. I usually never have more than one date.
I think natural selection selected me for extinction.
