The answer is all of the above.
First you fuck her.
Then you marry her.
Then the sex stops so you kill her.
Repeat as necessary for the next girl.
But on a slightly more serious note:
F - Bella (BaDIK), Sophia (AWAM), Victoria (COBD).
M - Ann (LSS), Katie (COBD), Emma (Hillside).
K - Quinn (BaDIK, or she'd kill me), Therresa (WTHI, or she'd kill me).
There are probably 10 girls each who could be in the fuck or marry catagories. Can't think of many kills though.
