Here's a Hint, I L Y

You can get angry,
Hate me,
Scream and Shout,
But here's the problem Babe,
I've seen your worst,
And know your best,
I've been through it all,
And I'm still here,
Coming back for more.

So the thing you really need to do,
Is sit back and think,
"Is this guy crazy,
Or does he really care?"

And I'll give you a hint,
The right answer will surprise you.
