Yeeek.... fight night... I have to agree with you on that one. It sounds like the perfect "guys night out without the women" kind of night to me. That and a group of men meeting for poker. Good male bonding time...
But if he wants you to go it's nice you're going and there will be another wife there. Perhaps the other guy begged him to bring you so his poor wife wouldn't be femaleless for the night?
Great point about the fine line of independence and dependence. I can completely relate to that as well. It's a real balancing act. Perhaps a better way to think about it is connection? In all of it maybe we need to make sure we're staying connected to our spouses.
There is no arriving, ever. It is all a continual becoming.
