Falling in love and finding the perfect partner to go through life with is the dream of the majority of people, but there are times when they just want to take a break from their search. They see dating as an imposition on their time and energy, so they would rather just stay home alone. Going out with friends and to family gatherings is about as much socializing as they can stand, and they have drawn a line around their emotional life.
Being relationship resistant is not always a permanent state, but it can last long enough to be a concern for family and friends. They often see it as a depressed state of mind, so they do their best to match up their loved one with someone. It might seem like a good idea, but many of their efforts will fail simply because the person really needs to take time to concentrate on their own life.
