Don't look at the papers. Do the usual with the talk, listen, validate etc. The papers are for your L. As SH says, his circus - he is doing this for attention/effect. I also wouldn't engage in conversation about him moving out. Just let him travel his own path and keep your side of the street clean.
In terms of the birth. This is something you must decide on. It's something you need to be very comfortable with. Perhaps having your Plan B there as your Plan A with your H in the room, IDK, I think if you ban him you may regret that. You may even want H in the room and Plan B outside? It would be ideal to think it could snap him out of his fog but from what I have read, in terms of other sitch's this may well not be the case.
You have plenty of time. Perhaps talk to your M and D and even MIL. Why not eventually talk to him?
Sorry, no definitive answers on this one. It's far too personal. You have plenty of time to talk to those that are closest. But suggest you get there quickly in your mind so it is not 'on repeat' in your head.
