Do you stop liking someone when they don't like you back?

Sometimes, I cannot help but like someone because they like me, although I might not like them nearly as much. I think it's only natural to want to be liked. By the same token, if someone stops liking me, I find it difficult to like them still, I might admire some qualities about them, but not like them. I think liking a person and/or admiring qualities about them are two different things. One uses a thought process, appreciating specific qualities, and one is more emotional, and we cannot help how we feel only how we interpret things that cause us to feel certain things.
