What Do You Personally Say...?

Love is love, attraction is attraction. Granted, there is a predisposition to procreate, but personally there are some things that CAN'T be understood. Some psychologists propose that behavior is due to some kind of abuse or neglect one suffered as a child, but that is not something that always makes sense to me. I dont really know what else to say... I'm starting college to major in psychology because these are the questions that run through my head at random points. I hope that I can find an answer that isnt so esoteric or vague.
