Why do guys on gay chatroulette sites immediately lose interest when I reveal that I'm partnered/married?

It's the weirdest thing ever to me. Often, the guy is hundreds or thousands of miles away from me (the website provides location information), which means that there is zero chance of us meeting up anytime soon and dating, and yet they still become immediately uninterested and "next" me if they find out that I'm married. Why?My hypothesis is that a lot of guys on there are secretly open to or hoping for a relationship, so they don't want to "waste time" jerking off with a married guy. What do you think?
