What should I do? I ruined Christmas for my lovely kind brother and his amazing wife by revealing her tragic past in front of our entire family in a huge argument with my other awful brother who was belittling my boyfriend
How did this situation get so out-of-hand?
I felt uncomfortable about it, I don't want to talk about Christmas
Your Christmas debacle sounds like a lot of people were hurt and out of control. You and your brother need learn how to exercise more impulse control at family gatherings.
I don't like getting called out on my behavior, I'm very bad with listening to people and especially to my boyfriend who I don't like to argue with
It's unfortunate that this happened at your family gathering. You should reach out to family members and apologize for any of your wrongdoings or they may avoid inviting you in the future.
