Wife in mlc (but mine doesn't acknowledge), feels she must be "unattached" for a time to heal (next time she says that I'm going to ask how can she be unattached while OM is fused to her side?)
My W does not acknowledge either, and pretty much said the same thing about wanting/needing to be 'alone', which, like your sitch, there was and is an OM.
