First post here...just starting to GAL and 180.

Good thing because it feels like WH is angling to return to mbr. He keeps taking naps in my bed and complaining his back hurts. I've decided, when he asks, to ask him (calmly and serenely) "What has changed since you decided to move out of the mbr?" I'll hear him out, validate and end with, "I didn't ask you to leave, it was your choice and I understand that. I would welcome you back into mbr when we have a monogamous relationship." Not sure how he will react.
Thoughts?

Glad thew GAL continues to go well Buxom!

Regarding the MBR question, from your post it sounds like you're already on point as far as aiming to keep the talk calm and avoiding being over-enthusiastic, which is great. If he does end up back in the MBR, it's still important to avoid being touchy/intimate until he's showing serious commitment via actions to get his head out of his ass and win you back. Sounds right now like him wanting back in is just about him, and what's most convenient for him (i.e. cake eating).

If he says something ridiculous during the talk, Sandi2 often likes to recommend simply saying something short&sweet like "Really?" (With an incredulous look on your face) rather than getting bogged down defending yourself.

I don't have any specific advice on the wording you proposed but for what it's worth, from my non-vet perspecective, I'm not seeing any huge red flags. Definitely let him broach the talk; for you it's probably best if he continues to experience the consequences of his actions as long as possible.
