Dear Amy: My partner and I recently traveled abroad with her family. We are all adults. We spent six days with her mother, father, brother and sister-in-law. We both knew that there would be the usual frustrations associated with spending time in close quarters with her enmeshed family. We stayed in vacation rental homes, where each couple had their own room. During our time abroad, it became apparent to both of us that her family’s dynamics stifled our experience.
