Even though I didn't see the problems in our marriage, in hindsight it was flat and unexciting. It didn't have the spark of joy it should've had. I get very excited thinking about how differently I'd do things in the future, and how good our marriage could be. That's jumping ahead though. I learned not to share any insights or hopes with my wife as she's not at that place yet and can't see it ever happening. I dare not mention such things as she almost seems to take it as a challenge to ensure the opposite happens.
Its your job to make things exciting for yourself, its not your job to make her feel happy - that is up to her.
We are all responsible for our own happiness and mental health.
We can only change ourselves not others.
Make yourself into a person only a fool would leave.
