I wish I had fought for more custody. I have 50/50. 50/50 is not good. Mentally healthy parents or not, it is best if school age kids go to one home during the school week, and save their transitions for holidays and/or weekends. I had wise people tell me this, but I was so certain that being equal was the best way to get out and away from him as quickly as possible. Narcs are going to fight you no matter how reasonable you are. I hope your mediation was successful.
