i agree with tom_paines comments about the term "love" and the phrase "i love you". as with any phrase the more its used the less meaning it carries. i(we) use it very sparingly in my(our) relationship, when we do use it carries greater meaning. if only people could say "i love myself" or "i love my life" with as much certainty and conviction as they seem to profess their love of another person...
on the subject of polyamory, i have long felt and argued that there is not "only one" perfect person in the world for each of us...and that our goal is to find "that" person. i strongly believe that there are emotional needs and emotional readiness that make a person "right". someone i met in my 20's may not be the person i would want to have a relationship with in my 40's. people twist themselves into all sorts of psychologically damaging knots trying to hold onto the myth that "til death do us part" is some kind of ideal goal...how about "to have and to hold as long as we are both content and able to give each other emotional intimacy"?
