I agree with Dia you need to get out in the evenings. I would make plans to go out on a Friday night. Break up the status quo a little, make pizza night up to the kids another way.
You are turned off by you wife because she is hurting you. So get busy, no idle hands or minds. Fill your love buckets by doing something you enjoy. Not good for anyone for Papa Bear to be grumpy. Get out in front and lead, dictate the pace of the game. Do you want to play offense and score or play defense? Go a little deeper in the playbook, your wife is handling what you are running now. The objective still is win-win-win for you, your wife and your family.
Cheers
