Does anyone know what happens when you have to co-parent who someone who point-blank refuses to work with you? ExH has lost school uniform but refuses to replace it. We had agreed DC would be vegetarian; since splitting he has been feeding them meat - didn't tell me, I found out from the older DC. DC was injured and I didn't want them to play their sport last weekend - exH took them anyway. Again I found out from another parent, exH didn't tell me. When he takes DC to dance class he loses uniform, drinks bottles etc. Emails asking him to replace them go unanswered. I can't not send DC without her stuff as then she would miss out. He didn't know what food to give youngest DC to take to childminder, instead of asking me what foods DC likes he asked the childminder. He just refuses to engage in any debate and seems to enjoy being as contrary / making me as upset as possible. He was very emotionally abusive towards me when we were together as well as violent on one or two occasions. He barely saw DC before we split but applied for full custody. He has always been a very "difficult" sort of person, not a team player and loves to quibble / annoy. Hates to be told what to do. Etc. I can't afford to keep replacing equipment. He is behind on his child maintenence also. Help!!! I don't know how I can do this for the next few years.
