I did the math - it's possible of you do a different guy every week for nearly two years.

Given that Ronnie's been in a relationship - a serious relationship with Louie for around about the last year or so in book-time, it would mean that Ronnie would have had to have been either A) cheating on him mercilessly, in which case Anita would have gotten on her high horse about it, or B) whoring herself out without Anita's knowledge back when they were BFF and Ronnie was as happily single as Anita, though a little bit bitter about her previous marriage.
