Singing Ginger: Jane and Jimmy

So have you ever had one of those problems? I am not talking monthly problems or family problems or even cash problems; I am talking weird feeling problems. The one you aren't 100% sure is even a problem until one day it hits you that it is. I have one of those problems right now and I can't say if I know at all what I should do about it.
Hypothetical situation time!

So my friend...Jane...is out of school and free for the summer. Jane is single and has been so for the past 7 months; before that Jane was involved in a wonderful two year relationship that ended mostly for the sake of Jane going off to find herself in college and...Jimmy...who was staying to finish his last year in high school. Jane and Jimmy eventually over came their heart ache sometime over the course of the school year and were able to start communicating again. Jane got back home and met up with Jimmy a few times just to hang out (Jimmy had a new girlfriend.) One night Jimmy told Jane that he had broken up with his girlfriend, and that he was looking forward to a blissful summer of singularity. Later that night Jimmy kissed Jane and everything went up side down. Jimmy and Jane decided it would be best to remain friends because Jimmy didn't want a relationship going into his first year of college and Jane thought it might be a good idea to mull this one over a bit before rushing into what would probably become a very serious relationship...again. So now needless to say Jane is very confused and doesn't really know what to do with herself. Both have promised to be honest with each other about other people they might fooling around with, which has yet to be a problem for Jimmy because Jane never gets asked out on dates, but which is proving to be slightly more difficult for Jane. because Jimmy is a big flirt and all the girls like him. Jane is not a jealous person, and I am not just saying that on behalf of Jane because she is one of those people who would say that and then go mug some chick who looked at her man. Jane doesn't do the whole jealousy thing...at least hasn't up to this point...The hardest part of all of this is that even though both Jane and Jimmy have promised to be cool and unemotional and unattached for the sake of their hearts, it just ain't going down that way.
