It all depends what is your relationship with this man
It means you are DIAMOND. You simply are the best!!! NO Doubt.
It depends on the context of the relationship. It may mean he sees her as inferior in some way or childlike. He's the parent in the relationship.
It depends. Is the man your father? Otherwise it means he's a tool and he's trying to be cute. Ugh. It sounds like he needs some new lines.
My classmate who I love and who loves me texts me calling me princess and baby even though I told him that I can't date...
