My beloved and I have also started a similar game...
One he was beating me at, and of course I couldn't have that!
Here's how it would usually go:
Him: I love you
Me: I love you more
Him: I love you most
Me: I love you more than most
Him: I love you more than that...
Me: I love you
Him: I love you more
Me: I love you most
Him: I love you more than the heavens have stars
ME - ??? STUCK ON STUPID. Crickets.
Then I say... Well, I love you... LOL!
So, I had taken to saying, "Well, okay... Hmmm... We are going to have to revisit this one later..."
Last night in the middle of the night or in the early morning hours, depending on your perspective, I had an epiphany:
Mere words cannot express the depth or breadth of my love. It increases exponentially daily, to the point that it is now incalculable. When you say you love me more... Well, that my love, doubles the rate of my love's growth to the point that it surpasses yours instantly. So remember, I love you more right after you profess you do.
BOOM. Game over.
And in the end, it's a WIN-WIN!
He not only loves me... When he got this and had a chance to talk to me about it, I KNEW he actually GOT IT and GETS ME!
That, dearhearts, is the reason I love him the way I do. He appreciated what I said COMPLETELY.
And, I know he's probably cooking up something to best it with! LOL!!!
