Are you Just expressing yourself and you dont mind if the other person says it back or are you requesting/demanding the other person to say i love you back?
I have only ever told two people I love them. My first husband and my second and anyone else *boyfriends who said it, I never said it back cause I didn't really love them
I'm expressing myself, and I hope they have some kind of positive reaction. If I said "I love you" and they responded with "ok", I would feel pretty crappy.
