Only from r/AmIthe*sshole/ that we can find crazy family dramas.
Meet OP, who is upset to learn that her husband's ex, Emma, is planning to join their Christmas trip to California without prior knowledge or agreement. The OP expresses her discomfort with the idea of Emma staying in the same house, feeling it's disrespectful to expect them to act like a happy family.
She states that she won't go on the trip if Emma is included, emphasizing that she's not trying to replace Emma and is only looking out for her husband's court-ordered parenting time.
The OP's mother-in-law reacts negatively, calling her a selfish and ungrateful person and insisting that Emma is as much family as the OP. The argument escalates, resulting in tension.
So is OP the AH in this case? Let's see how Reddit reacts!
