The things I say:
"He doesn't deserve you."
No one ever deserves anyone. You like someone for reasons of your own.
Perhaps you can earn respect, but I am doubtful, since we tend to respect tall, male people with deep voices. Yup, there are studies.
Having feelings make you vulnerable. Stop having them and you'll be OK.
"I have no expectations."
As if that's ever true. You don't do something if you have no expectations, even if those expectations are as mild as hope. You just do stuff and hedge to preemptively manage the disappointment. When did that ever work?
Stop having feelings, it's better that way. I am certain.
