I need some help in answering a message from my ex without inflaming an already v fragile truce. We split a year and a half ago over his drinking and lies. It was a very brutal and messy break up and we only communicate over text/ email and it's strictly about the kids. He takes them to school/ picks up most days and has them over for sleepovers in the week. Weekends didn't work as it interfered with his social life and frankly this situation suits me well. I am NC with his entire enabling toxic family. And I've cut all contact with mutual friends. Necessary for my sanity. I have previously refused holidays because I dint trust him. Or his family. But he has now asked me to consider the idea of taking them away over Easter. Abroad. It's a big fat no to me. I have no idea what his drinking is like. He managed to collect them for drop offs mid week. But that means nothing in terms of what he does weekends and my experience of holidays is that it's his cue to get shit faced. I am not comfortable with holidays and don't see why I should give him the benefit of the doubt. We were together for 15 miserable years. But I don't want another row over this. Any suggestions how to deal?
