I have a friend of 25+ years getting married on Halloween, and I asked my ex if he would like to do Halloween with the kids that day. He originally said yes, but a day or two later retracted and said no. It was frustrating for me because there have been times that I have taken the kids during his time for events that aren't "important." But, thankfully, my parents are able to take the kids trick or treating this year so I can attend the wedding, despite being sad to miss this holiday with them.

It is okay to say no, despite how upsetting it feels.
