The wonder of Psych Central is you can be in virtual relationships in this world without the complications in the other world when I log out of my computer. There can be closeness without physical contact and their can be distance by logging out for the night. You can hover in the forum just reading other posts without saying a word.
So this is how you can create a virtual and non virtual world that gives you what you crave in terms of human friendship without the intimidating and scary aspects of a person being dependent on you or wanting you. You can be distant and close - everything is under your control in one sense.

It also overrides the fear that you will just make another victim by withdrawing. There are fewer rules and expectations here. People just disappear and appear again. It is less burdensome.
