As usual in English there are exceptions to the -ing usage. Some verbs cannot be used in the continuous form, or can only be used this way with a "special" meaning.
These include some very commonly used verbs such as: remember; forget; have; verbs of emotion such as love (except as used in a particular hamburger chain's commercial!), hate; the verbs of the five senses; consist; contain; want; need.
Even though you are doing it right now, you cannot normally say "I am remembering......". Instead, say, "I remember ...".
Never say, "Are you wanting...?" but, "Do you want...?"
