I'm considering taking DD on a trip to visit my XH's parents over the summer and visiting some friends up north (they're in CT, he's in LA, I'm in FL). My ILs and I are on good terms and they miss their granddaughter/niece (two of his sisters are there too), but would it be weird to go and not invite XH? He and I are friendly these days but I'm not really sure I want to vacation with him. But it is his parents so I almost feel obligated. WWYD?
