T, I understand you're irked about your W trying to set up a date, but ask yourself this- what is best for your kids? Do you think S3 would rather spend all day with mom AND dad or spend part of it with mom and part with dad? Because that is all that matters, what HE wants and needs. At his age he is not going to understand what is going on between you two, so you need to shelter him from that as long as possible. It's looking like W and I will be D'd soon, but we will likely still get together for the kids' birthdays because that's what they want.
I really think your motivation for this was anger and frustration and that you're trying to teach W a lesson. But all it's doing is making her angry.
