This really pisses me off. You are not a Sociopath, you're an edgy person with an overly attached girlfriend who has no idea what the term 'Sociopath' means. If you were a sociopath, you wouldn't care about your Girlfriend, nor would she care about you.
I've had my fair share of "real" partners as you would put it. I think my shortest relationship lasted about 6 months.
I had a ''real girlfriend'' for over a year, also, don't know what you define as real, seems like an odd thread.
I've had quite a few online relationships with both sexes. Everyone single one has been BS; I had no intention of ever actually taking it to real life, even if it would have been easy to. I just continue on, pretending to be interested in making it a real thing until the relationship inevitably loses its spark. Something is probably wrong with me.
