It's because I have a desire for a relationship, but I do not have the ability to handle one, will not interact with my partner in relationship-wise, and will become too stressed and anxious to keep it going, thus me and the partner will break up and then I'll be back on square 1.
It's weird when you think about it, but I can't help it, which is why for most of my life I was aromatic (sometimes I'd change for x amount of time, but that's about it)...
