Thank you Sandi.

I am much clearer on this myself this morning.

The separation is for me, to really decide what I want to do in future. I won't impose any rules on the separation unless it's to protect myself, such as financials. No point even mentioning dating etc - she's already taken that step. Plus, as people have mentioned, its unenforceable.

I will ask the W to move out as soon as possible. Having her in laws here means that her life will not be very impacted, even if she doesn't have me. She will eat cake unless she moves out on her own. She's never lived by herself ever before so it'll be quite a wake up call I'd say - unless she moves in with OM.

Even then, he's a 25 yo uni student so I doubt his living conditions would be as nice as our home which we designed and built.
