Ah, FS - I don't blame you for things getting heated. It seems obvious to me that your H is terrified about losing control: once you sell the house and formalise the separation agreement or divorce, he is not going to be able to call the shots. You are being entirely, entirely reasonable in what you are asking for, and it is in the best interests of your daughter's. He can't have a job of the type he does and expect you to work around him and do childcare at his convenience: that might be what you'd expect of a wife, but not a co-parent. Co-parents need set schedules. He knows that. He's terrified, isn't he? I almost feel sorry for him, though I kind of expect that as you stick to your guns and as mediation progresses and it becomes clear what he wants is not going to happen, then he's probably going to act out more. I hope you get that mental space that you need. x
