What does it mean if someone calls you naive

We have dated for a few months but then he said he wasn't in love with me.Sometimes, people may be called naive if they believe that they can fix others by helping them, loving them, believing in them, etc.You may even recognise what they are doing, but often naïve people don't want to upset anyone.The rather naive young man had been totally misled.Oh, you're so innocent and pure, they say, as if it's a good thing.

This happens almost with all at certain moments of life.You see their intentions as only being good and they use this to their advantage.Many people use it as a compliment of sorts.It's the opposite of being jaded or bitter from experience.
