Please reconsider therapy. If your wife won't engage in couple's therapy, then please consider therapy on your own. You sound depressed, and you are providing reasons to not bother taking action to be not depressed. I am worried by that.
Sometimes, yes. But you're assuming a result. Divorce is not the goal. Improving your own satisfaction with your life is. Hopefully, that will not lead to divorce, and that's the goal of couple's therapy.
