I always thought that loving someone means that you want to share everything with them, but I've come to realize that you also become very protective of that person. In a way you want to make sure that they never feel bad, down or worried. Even though you know they will inevitable have bad days, you don't want to be the reason for it.
Do you know what I mean?
He said: How are you feeling?
She said: I'm ok (even though they both know she's not ok).
He said: Promise?
She said: Yes, it will pass and I'll be fine. Please don't worry.
He said: I worry only for you and I'm worried.
She said: Please don't (trying to sound as cheerful and normal as possible). I'll be fine.
He said: I know you're a strong girl.
