You might have seen my other post. But this morning all too typical event. DSS invited his Dad, me and Grandma to school play. The ExW, who is also planning to go with her M&D but wont "allow" DP to attend any school events, declares we are "banned" because of me so DSS sends text that I cant come and DP and Gran drop out too. So school drama turned into more of a vindictive-Ex horror show yet again...Have not responded to any of them. Is this best approach?
