Hi Kathy.
It sounds like you are having a hard time at home lately. If I may, I'd like to share an alternative perspective from what most are offering here. If I was in your shoes right now, my inclination would be to focus my attention on all the things I love best about my wife. Seriously. For real. If today, right now, I found myself in the position that you seem to be in, I would begin to make lists of all of my wife's positive aspects. I would make lists of the positive aspects of us together. And I would write these lists everyday. I wouldn't necessarily share them. (Or maybe I would, if it felt right.) I wouldn't write these lists for any ulterior motive other than to make myself feel better. I would do whatever I could to feel better about my wife. I'd do what I could to feel better about my family. I'd do what I could to feel better period.
This might sound a little crazy, but think about it. What do you have to lose by concocting a million little ways to make yourself feel better about everything and everyone in your life?
I am a firm believer in the law of attraction. I feel that for me, if I want to connect with the loving, understanding aspects of the people in my life, then it's important for me to focus in a deliberate way on all the ways that those qualities manifest in that person... by making positive, good feeling lists.
I'm not suggesting for a moment that this is going to save your marriage. In fact, if those positive qualities in your wife are so suppressed as to be nonexistent at this point, then focusing on them may actually hasten the end of the marriage. But if all those qualities that you've loved so well about her over the years are just below the surface and/or still very evident, then you're more likely to see much more of those qualities manifesting in your day to day interactions if you take the time to look for them and acknowledge them, even just to yourself.
The main reason to take the time to acknowledge your wife's positive aspects in writing though, is just to feel better. And if you can make yourself feel a little better with a simple list, well, that's worth a lot. What's better than feeling better? And seriously, what do you have to lose by showing yourself that you can make yourself feel better with a simple list of positive aspects. What might you gain? Try it once a day for a week and see if it helps.
Big hugs to you!
