We call each other "love"
We have been friends for 6 years. He has his girlfriends and his life, I have my own thing. But... Every time we are together, alone or with mutual friends, we kiss and cuddle. Its been going on for 2 years now.
Whatever else we do, we never tell to anyone. We are not together, and we do not have aspirations to have a conventional relationship.
We call each other "love".
I assume it will last until one of us falls madly in love with someone someday.
