Thanks everyone for the replies. I would like to address each of them soon. For now, suffice it to say that the nasty argument is behind me and I am actually having a nice weekend.
I have a question for the group: I would like to visit my sister with the kids for the upcoming jewish new year. My W does not want to be away from the kids for this holiday in particular - I'm not sure why. We are at an impasse. Here are the details of the proposed trip:
It would be 3 days (sun-tues). It will be the only time my nieces will be there. We will be home for the rest of the Jewish holidays - there are many more holidays within a week or two. Most importantly, my kids really love going and have been asking me for weeks. Although my sister lives 3 hours away, my younger kids have not seen their cousins since the bar-mitzvah in may.
We are still legally married. There are no custody issues. Do I put my foot down? Do I appeal to her and simply fold if she says no? I am as much of a parent to these children as she is. Prior to BD I deferred to her for all these decisions. The kids will be going through a difficult year anvd a trip to their aunts is something they really love. My W will have to understand that there will be holidays where each of us will not be with the kids. Or, do I concede, like I did for the first days of Passover?
