DH just told me has decided to go to Las Vegas with his buddy during spring break, the same time his kids are coming to visit (ages 9 and 12). He claims its the only time his friend can go bc he has 7 kids but they are in a camp the week of spring break. However, i know that is not completely true that they could not go another time when DH kids are with their mother. Am I wrong in being upset over this situation? I worry the kids will feel DH picked his friend over them. DH wants me to lie about where he is and I'm not up for that either. His kids are smarter than that. It's causing a lot of strife. Advice, please.
