BTW, the reason your h is looking to you for an answer about setting up the meeting because you are the one that sent him the text with the ultimatium. People who are thinking rationally would go ahead and have their lawyer contact spouse's lawyer, but when they are in crisis, they aren't thinking like rational adults. Your h, if he is in mlc is a teenager, looking to "mom" (you), for the answers.
I have been where you are right now and I know how you feel. However, you will get more with honey than vingear.
I am sorry if I have offended you with my responses, but I try to be as honest as I can w/the posters to help them avoid the pitfalls that I experienced a long time ago.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
