When Your Parents are Dating………Other People

My parents divorced when I was 13.  After a couple of years I gave up all illusions of them ever getting back together again.  This post isn’t about some wish that they would reunite as a couple after all these years.  No, this post is about dealing with your parents as they date other people.

In the thirty years that my parents have been divorced, they have each married other people.  One marriage ended in divorce and the other ended when a spouse died.  So, they are both single and (God, I hate how this sounds) dating again.  My dilemma is:   what is the proper etiquette to follow if you don’t like someone your parent dates?  Everyone is an adult in this situation but that is still my parent.  I feel the need to look out for them and protect them from harm.  Should I voice my opinion even if it is based on a feeling and not hard evidence?  Should I stay silent and supportive and hope they figure the person out for themselves?

I’m struggling here.  Any advice would be appreciated.
