Don’t ask her questions you already know the answers to or you can’t handle certain answers.
Don’t get mad if someone else does for her what you did not do.
It’s about feeling appreciated; it’s about knowing that at some point, someone, but mostly You, thought about her, about her feelings, about what she likes.
Someone like her will never tell you to do things for her. If she wants something, she can get it by herself.
The only thing she can’t have it on her own its happiness.
