I think this is awful for her to do. I guess this is where her priorities lie? You need to have a sit down heart to heart talk with her. Maybe even counseling.
I would never do that to my husband and I don't even get why she would want to.[/QUOTE
So his DW isn't supposed to spend time with her birth family? The OP is open about the fact he doesn't enjoy the big family get togethers.. Remember they are both retired now. The takeaway from this is sit down early in the year and block off the days that work for couple trips and seeing family trips.
Of course, but what I was meaning is she should be taking his wishes into consideration also and make it work. Spending time with her husband for vacation should be a high priority. Especially when you know he is unhappy about this situation. Obviously a lack of communication and consideration involved here.
