Trusting untrustworthy people

Last night in a dream, I was some beautiful woman with an untrustworthy ex-husband.  He was one of those people who loved all things beautiful without giving a thought to loyalty.  And in my dream, I realized something: being on the outside--not in a relationship with him--he suddenly became more more trustworthy in a way.  I mean, I couldn't trust him with my heart or my body or my future or any of that important stuff, but I knew I could always trust him to love me in his own superficial way for my beauty.  (And, to a certain extent, I knew he admired me for being unobtainable, lost (to him) forever.)
