It's part of Love

 You accepted them for all that they are, the good and the bad.

Because you're nowhere near perfect either. 

But that's part of loving someone. 

Accepting all of them. 

Not just picking parts you like. 

Learning the little things about them.

How their breathing changes when they're asleep.

The sound of their laugh.

How beautiful their eyes are, especially in the sun.

Hearing them as they laugh in their sleep because they're dreaming.
