Sounds like she is all over the place. Kind of like a hurt animal that is cornered, they are the most dangerous true. They also can choose to fight or let someone help them and be vulnerable. Usually its a little of both, more fighting at first, then vulnerability.
Sounds like to me she might be reaching out in a perverted sort of way. Maybe the ML thing or the stepford wives bit is a little of that, even if it is uncomfortable. What have you got to lose by positively responding to that? When was the last time you acted lovingly affectionate?
