Never. 
Every day.
Sometimes twice or three times a day.
I never hear it and i cannot bring myself to say it. Isn’t that dreadful?
Every time I talk to her.
I tell Spidyreb I love him every opportunity I get and he does the same. Emails and IMs do look wrong without saying it and conversations seem a little empty without it. Many times I’ll pop out with I love you and it means more than just those three words. He’ll do something cute or say something very sweet or it may be just the way he looks at me…saying I love you just summarizes many loving feelings. I love you, Spidyreb!!!
Well, I always tell my parents I love them at least a few times everytime I have the chance. I don’t usually tell my little brother but sometimes I do. I don’t usually tell my closer friends that I love them but I might say stuff like love ya to them.
My fiancee and I are firmly in the “many many many many” times a day column. Perhaps due to having spent a lot of time apart. I think we might set records.
We once had a firend ask, “Did you guys have a fight or something? What’s with all the I love you’s?”
What can I say? I love her…
My SO and I aren’t very verbal about stuff like this, and it doesn’t bother me. He says it when he feels like it will matter, and I throw it at him every once in a while.
I think, (since this is IMHO), that the less you use it, the more meaningful it becomes. It’s not the words, but the sentiment attached to it that make it important.
I don’t think it necessarily follows that it is meaningless if you say it a lot. Every time I tell Mrs. Arken I love her I mean it.
I don’t have to tell my PS2 that I love it. It already knows.
Oh Koffing, Koffing, Koffing! It’s just using you for the discs!
