Had two couples staying with me and DH over Christmas, as like last year. One of the couples this year spent the entirety of Christmas day, Boxing day and the day after in full meltdown having arguments, crying, storming out on each other (we are all 30's). They flew in from a different country to join us so its not like they could just go home. They went away for a few days to visit family and all seemed good until they returned for a BBQ and then continued to spend the evening in a deep and very teary conversation in the front room while DH was outside cooking, resulting in us eating alone while she cryed and he looked awkward in the front room. They have had a stressful time since recently moving overseas with finding good work, housing and establishing themselves but AIBU to think that they should have known better then to bring that drama into a very busy very public Christmas with around 12 guests. I did ask if she/ he was ok and needed anything but they just kept saying they will be fine just needed to talk to each other. I cant help but feel I have been on eggshells in my own home for the last few weeks and although they apologized when leaving, it feels like my time off with friends has been ruined by their drama and inability to have these dramas back home or not in front of a group of people trying to enjoy the holidays! AIBU? Should I bring this up to friend as they are expecting to see us in a month when we go to visit our family in the country they now live and I feel like I don't want to spend more time going over the same things again?
