I am very self-centered. I find it hard to share my life with another person as a partner. The more intimate a relationship is, the more it feels like I'm being engulfed, or that I'm losing my identity as an individual. That perversely draws me to potential partners who are less likely to "consume" me, either because they have their own issues with getting too close with someone, or because they're just not the sort of person that I will ever fall for in a way that would endanger my individuality. I read an article just the other day about how people with intimacy issues are often drawn to one another in relationships, because neither of them wants to get too close to the other, and so they tend to fit together in some sort of messed up way.
