girls are annoying

[irishpint]

ill make this quick. together 4 months. break up for 2 weeks. during those 2 weeks she poses naked for a calender (right...) however it never gets published. now we've been together for 4 more months. Thing is, she is friends with this guy who took pictures of her. naked. he takes her out to dinner and buys. they watch movies together. can i, with justification, do any of the following:
1. ask her if they ever had feelings for each other
2. ask her if they ever hooked up/were in a relationship
3. ask her if he is a complete dork and i have nothing to worry about
4. call her a whore (please say yes)

WHat would you do? How can I explain to her how much this bothers me? Would it bother you?
BTW I am in Tacoma finishing up school and she graduated. We have plans to live together next year when i go to dental school.
