I've been married for 33 years this summer. We have obviously had BIG some ups and downs.
We only know a few couples married as long as we have been. (I mean, happily).
But every single couple we know who has been married over about 20 years, has ONE thing in common: One or both of them did a chunk of forgiving. They let go of some past hurt or grievance, and they stopped bringing it up.
I think we don't teach or focus enough about how to forgive in our society. It might be something for you to consider doing, regardless of how this all turns out.
Also, I read this quote: "Holding onto anger to punish someone else, is like lighting yourself on fire,
to get smoke in their eyes."
Food for thought.
