In English, the "to-infinitive" or "-ing" form is often used after certain verbs like "can't", "don't", "want", "mind", "give up", "is worth", "prefer", "fancies", "is too", "promised", and "avoid". The "-ing" form is used when the action is ongoing or when it's a habitual action. The "to-infinitive" form is used when the action is a future action or a purpose.
