Its odd, the technical terms being danced around are
Monogamous Infidelity Polygamous Infidelity
These two are usually easy to distinguish from one another.. but your case is a bit of an oddball...
Usually the Polygamous WS will try to act as if, not demonstrating any beligerence at all... while the Monogamous WS will be overtly rebellious, avoidant, and even cruel...
Yours is doing BOTH, so I don't know what to say.. Is this how it was last time though? Or was it a more clear distinction before?
