I am not going to promise you we will be "together forever."
I am not going to tell you I love you 'to the moon & back.'
I am not going to say that you look hot.

Instead, I will promise you each day that I will stay the day.
Instead, I will tell you I love you, but show you how much (way more than 'to the moon & back').
Instead, I will glance at you soaking in every inch of your beauty, sit back & shockingly say, "wow."

If I promise you that we will be "together forever," you may get some lazy relationship where we put our effort into the cliché land of time that we call, tomorrow. If I promise you each day, that I will stay the day, then I'm sure we'll get a relationship where we put our all in, every single day.
If I tell you I love you 'to the moon & back,' then I am giving you a limited love. My love for you is unlimited.
If I tell you I love you, & show you how much, I'll spend the rest of my life showing you, & you'll get the rest of yours to see.
If I tell you "you're hot," I'd be understating it, & you would feel like a hunk of meat. Your beauty magnifies, & I will remind you everyday making sure you feel your beauty as I see it.
