I have not said the L word in months. I am using your 37 rules, though at times a slip on some things. I do not ask about anything in her life. I do try to share things, occasionally, about my what is going on in my life. I only really try to talk about the kids or if something needs to be done with the house or vehicles.
In this arrangement, I have my few nights a week where I do my own thing - mostly the outdoor activities. Every so often I meet up with people for a night out. So I GAL. I have minimized the cleaning I do and the house shows it. She is talking to me about taking the kids away for a weekend to clean the house. I am planning activities for just the kids and myself. I do get my own time, and if I let her know in advance I can have other plans. This is what I get out of the arrangement.
So in the sitch where she does leave, takes the children and gets a lawyer - what are my options? I know I can drop a letter at the school saying the kids cannot be pulled out without mutual consent. But what about other things?
