My advice is to envision what you want the future to be, and do what you need to do to make that happen.

That can look like a lot of different things. Sometimes it's having a hard and direct conversation. Sometimes it means employing subtlty: jokes, passing comments, body language, etc (all the more important to understand and purposefully engage in these skills when communicating with someone who is not autistic). Sometimes it means putting on a mask of civility. Sometimes cutting someone off entirely.

Revenge in my experience is usually not satisfying.
