Thanks, and straight off the press (i.e. an email arrive 5 minutes ago) I have another difficult situation with my ex.
This is typical of how it goes.
My son opened up to me last night about being bullied by one kid at school. He doesn't want to go to school camp because of it.
I emailed his teacher last night (CC'ing my ex) and emailed my ex separately letting her know what was happening and that I would go to the school this morning AND she was welcome to come along. I got no response.
After meeting the teacher I emailed my ex with notes on the discussion and the outcome and got the response "Thank you for dealing with this. I did the same last year." (Sans letting me know of any issue, action or outcome - so who knows if it's true).
This afternoon I emailed my ex asking if I could take our son to the Information Session at the school for 1.5 hours next week (Suggested by the teacher). Her response was "Are you stupid? Read the consent orders."
I responded "I'm not sure what that means. If you were going to take him that's fine, I'll be there too."
Her response, "You are stupid. It's my day with the boys. Don't go to the school or I will not take him to the Information Session"
This is a typical exchange that happens every 2 or 3 weeks. If I have the children she bombards them with Snapchat messages and on her days with them I'm blocked from school excursions (once she said she would hold my boy home from school if I went as a helper on the excursion) or school activities.
You have every right to attend school events, excursions and information meetings for your children. Even if these days fall on 'her time', she cannot dictate what public areas you attend in your time. The same goes for any weekend sports, etc.
In fact, a court would probably encourage you to do go! Although your ex isn't breaching orders by witholding your son from these events she is alienating them and more obviously, not putting their interests first. It will definitely not look favorably for her. The fact you have attempted to reason and compromise will help you.
Document and screenshot everything!
