She's moving out in two weeks? I'd let the issue of the concert slide. What could you possibly gain by confronting her?
My b@lls. I'm sure it would do more bad than good, but I've always been a bit passive with her. If she wants space, that's fine. If she wants to run around with other guys, I won't be around as a plan B.
Does she see you as Plan B? I'm not remembering the details of your situation, but I would interpret moving out as a sign that she doesn't think you should have a say in her life unless you have a clear agreement that this is a separation for a limited time for the purpose of working on your marriage and you have agreed to ground rules.
If my H announced he was going to move out on X date (not as part of an agreed upon separation), I would assume I had no more say in his behavior outside the home unless it directly involved our kids.
Unless you have a separation agreement, I don't think saying something is "taking back" anything.
Me: 44 H: 44 Kids: 20, 16, 16, and 10 Together/Married: 22 years H announced he was emotionally detached and considering D: 4/4/16 H announced he is going to try to stay and reconnect: 5/1/16
