Hmm. That Cathexis bit was interesting. So, if I'm understanding it right, basically the more time a person invests in a lover, the more that person means to them, regardless of whether they are abusive or philandering or what not? That would certainly explain why people remain in bad situations.
I knew a girl once, who was living with an emotionally abusive jerk she had met in rehab. He would make fun of her, on two occasions hit her, and was getting her hooked on pills again. A mutual friend offered her a place to stay, a way out, and she took it. We went, picked her up, got her situated, etc. The next day, she called him to pick her up. Thing is, "She loved him". So, for whatever reason, she's willing to endure hell to feel love. Years later, she told me that she was just lonely and she loved him because he paid attention to her. She also loved him because he was passionate and charming sometimes. She loved him because he was passionate, handsome, male, and was there.
Then I look at my parents, both of whom never once played the field, who met each other in a very unconventional way (My mother picked my dad's pocket when they were on the same base in Germany), who hung out on a regular basis, and eventually married because they were being stationed at different bases and couldn't imagine being separated. Sure, they fought, but my father has never once [intentionally; chronic foot in mouth] insulted my mother, has never laid a hand on her, and has stuck with her and cared for her through the worst of her deliriously bad depression. He's been willing to give up his entire life to care for this woman, because he simply couldn't imagine a life without her. He's not a passionate man, given over to emotions. To him, that feeling of attachment was enough to be called love.
Is there a difference between these types of love? Is the love of my parents any more or less valid than the love of my friend? What makes one brand of love so chaotic, and the other relatively serene?
