Stative verbs refer to states (experiences, conditions, emotions, senses) and not actions. They use the simple tenses and do not usually have a continuous (progressive) form that ends in -ing. They can however be in the continuous form when they are used to describe actions.

A stative verb is different from a dynamic verb. The subject in a sentence takes a dynamic verb to show a continued or progressive action, which is the opposite of a stative verb. A stative verb, as stated, shows a state of being.

She loves him madly and will do anything for him.
Not: She is loving him madly and will do anything for him.
 
I see from your look that you do not like me a bit (Stative verb = understand, realize).
I am seeing your mother about your breaking my windows (Dynamic verb = meet).
 
I think that soup of hers was like fruit juice. (Stative verb is used to express an opinion.)
I’m thinking about the world getting more polluted by the day. (Dynamic verb is used to consider something.)
