Going, Don't sweat the crying. You can't internalize it and you have to release and regroup. Just try to not let her see you do it. Many people would not put up with what you are. Is it any wonder why the divorce rate is so high. She knows you are her rock. She also unfortunately knows that she can do whatever and you will still be her rock. You need to find a balance of being her rock and being your own man.
You most definitely need to get out on your own. Reconnect with Friends that you have lost touch with. Take a road trip of your own. Break the normal routine. You are predictable to her. She doesn't have to second guess how you will handle things. Be passionate about something. I can't get a read on you Going because all you talk about is your wife.
