Not content with one relationship
I've been in many relationships, and I always end up breaking up because I feel that I'm not being loyal to my partner. I usually find myself interested in other boys and wanting to pursue relationships with them - IN ADDITION to the one I already have.
It's generally not discontent with my current beau, but I guess I always want the chance to really get to know more people and I feel like I have the capacity to love more than one person at a time. I'm not the jealous type, and obviously wouldn't care if he had other girls he was seeing - though it'd be worse if they were just for sex, and not because he actually cared about them - if he really liked her, I'd probably encourage it.
I've looked into this feeling, and have found articles about Polyamorism that seem similar to what I feel. However when I've tried to talk with my boyfriend about this, he told me I was a nympho, had no real emotions, and it was just wrong.
Is what I'm feeling normal, or do I really have a problem? I don't mean to hurt anyone (especially the boys I date because I really do care about them) but I just want to be able to fully love more than one person, without having to let go of others that I already love.
