<human>: Can you give me a shortened version of the text?

Well. First things first, we have been together for ten months and going strong. But he (M19) recently brought up the topic of an open relationship for this summer so he could enjoy his last summer to the fullest capacity (only for the summer though.) I'm (F18) the only girl he has never cheated on and I'm grateful for that. Although, I'm iffy about the situation. I don't want this to be a something that tears our relationship apart. He says it is because he wants to be able to have his last shabang before we go out to college. I see it as he wants to have his cake and eat it too. As In have the benefits of being in a relationship and also the benefits of being single. I told him I would take it into serious consideration. I laid out some guidelines if I would say yes: he would always have to let me know what is going on (who he is seeing, where are they going and so forth), no going behind my back through any of it, always condoms ALWAYS!, he cannot blow me off so he can go have sex with that neighbor girl down the street, and I have the right at any moment to call it off if i start feeling uncomfortable with the situation. I guess my biggest fear is if I don't agree to it he will just do it anyways behind my back. Also, that I would turn into a crazy jealous MegaBitch which I don't want to happen. I am stuck.
