Please help me with some advice. Ex is very emotionally abusive, one of his favourite tactics being stonewalling. He does this constantly when I try to make any arrangements for our child. Even exchanging medicine becomes days and days of asking (between derails of his, attempting to spark an argument about unrelated pettiness) to arrange to meet. We exchange our child through school drop/collect, so we don't meet if it isn't organised. I think he's decided never to see me or speak to me again, which is his choice, but how on earth do you make this work with almost 50/50 care? He has attempted to frustrate medical appointments, basic swimming lessons etc, and refuses to give any money of any sort (I've applied for child suport). Any advice would be gratefully received!
