When you can’t live your values. Are values and a manual the same thing?

I am getting divorced. I don’t believe in divorce. I trusted my husband. He betrayed me. He was not as committed as me. I fear that everyone else is like him, looking for fun and affirmation, then to stray if things not quite right.
I feel as if I am not living my values, but I don’t have a choice.
I also wonder if values are just a manual… and then I’m screwed… I believe in marriage (or did) and others don’t and there is no way to tell what others are truly believe or are interested in.
Whew. Feels so sad.
