She's not sticking to the parenting plan
Our agreement says I get the kids Wed-Fri every week. Last month she had to keep them 2 extra days without asking, then 'forgot' to tell me about a doctor appointment they had. I'm trying not to be petty but this is getting frustrating. We use a co-parenting app now but she barely responds. Do I bring this up or let it go?
This would drive me crazy. The kids need consistency and so do you. You might need to have a more serious conversation about what the actual agreement means.
