To me, the meaning is in the first verse. She seems to be talking to a man who is known as a heart-breaker. A guy that Perhaps even uses women and then leaves them. But Pat is saying that even though she knows this about him, she still wants to be with him. Then the third verse line of "Before I put another notch in my lipstick case" seems to be saying that she is really just like him and that's why she wants to be with him. Like saying "push me away like all the other girls, but unlike them i'll keep coming back.
