I am recently divorced from my ex husband and we share custody of our children but he has them on the weekend of Mother's Day. He wants to take the children to his parent's house that weekend to celebrate with his mother in another city. AIBU to think that I should see my children that day or should I suck it up and celebrate another weekend with them? I would let him see the kids for Father's Day but that conveniently lands on his weekend too so there's no bargaining power.
