I get you, yes. And yes, I did agree to have this walk with him - out in public and with my own car at the ready - because I wanted to get some forward motion on financial separation. That was achieved. My mistake was to then basically enable him to duck out of the school event, which he's uncomfortable about because of his paranoia, and let him get his feet under the table at my house. I let my guard down because we'd had a fairly amicable conversation, and because I felt pity for him. Given the way it ended up, and given that my sense of self preservation is greater than my pity, that won't be happening again. He doesn't have a key to my house and his levels of comfort at school events aren't my concern. He can overcome it, or arrange a child minder to pick up Youngest on the days he is responsible for. I am continuing with NC and GAL and feeling very steady about it. If he doesn't stick to what he has agreed regarding finances, I won't contact him about that, but just go through a solicitor to buy him out of the house and go through our government agency for child support costs. That is the plan and I am - and have been (only a few days, I know, but all the same) sticking to it. I am open for more suggestions as to how to go forward, but I think what is most useful to me now is advice about GAL and how to best support my children, as I don't plan to have any interactions with him now.
