The Definition of Love...

With Valentines day come and gone I've been contemplating the meaning of love.. I would say that I'm in a loving relationship.. me and my partner, R., have been together for what will be 7 years in July.. that's longer than a lot of marriages.. so the day of St. Valentine got me thinking.. Why does R. love me?.. and he obviously does because he puts up with my whining which has become more frequent and loud since my various health problems have put me in a snarky, whiny, moaning frame of mind of late.. what's the attraction?.. I had gained over 25 pounds since we met (and so had he come to think of it).. we've, since this time last year, managed to take off the 6 years of blubber we had accumulated due to showing our love through our stomaches.. I guess if my love for him hadn't diminished because of his growing waste line then why should his for me?.. but I have observed that men are more visually stimulated then women.. but I guess my limited knowledge of the opposite sex is just that .. limited.. and the meaning of love is beyond my grasp.. but not the love itself.. so I guess I shouldn't over analyse it or I might miss out on the actual experiencing of it..
