My friend with benefits told me she misses her ex boyfriend, what should I do?

Her ex has a girlfriend now. Clearly she has unresolved issues, and she sometimes wants to talk about guys she has been with... I am uncomfortable with it and told her that before. I am in a dilemma if I should cut it off. What do you think?

She didn't saty it in a way to end things up with me, she just said it as a "by the way" thing.
