Still Mrs?

Is "Mrs" still applicable to me? I have been divorced for 6 years. Both kids are grown and married. Ex and his wife live in the same small town as I. Actually, all of us get along quite well. Still, I`ve wondered awhile what appellation is used after divorce? I was married almost 30 years - and have no desire to change my name. So... The question I put to you is, am I relegated to "MS", or is there another option?
