I hate socializing. I tolerate work, but avoid talking to others when avoidable. I always turn down any social invitations. I have one friend who lives thousands of miles away. We talk on the phone occasionally, and text.
I am married. I enjoy my wife. She seems to love me. I don't really understand how or why she and I work, but we seem to.
Part of it may be that while she's more social than I am, she's not very social herself. When she does do things with her friends or family, she seems okay with letting me choose whether or not I go to. Which I usually don't. I don't know if that's mental health related at all. Maybe its just a personal preference?
