The attachment stems from the woman allowing the man she wants to be loved by going as deep as he can inside her.
The closest example I can give is in Baby Boy after Jody beat it up then said to Evette,
“You gon cook?”
“You gon clean?”
“You gon make them tacos like I asked?”
And she was under mind control like, “ima cook, ima clean, ima make the tacosss.”
She completely forgot he was still smashing his 1st bm and failing as a partner and father.
If she had moved on with Rodney she would’ve still been mentally fukking Jody and that has nothing to do with them sharing a kid.
