Am I ready for this again?

Ok so I've been thinking…errr… steaming about this all day. I am gradually starting to see it from his point of view. Its possible that from his point of view I have no right to get pissy about him ditching out on our plans because he doesn’t have any comittment to me yet. From my point of view, my feelings were still hurt and I don’t think people should flake out on other people, even if they are only friends or have a yet-to-be-defined relationship. But from his point of view, I could possibly be acting like a psycho stalker. The fact that he is a good guy but hasn’t yet apologized and is in fact now ingoring me says that he doesn’t think he did anything wrong and shouldn’t have to apologize. That is one nice thing about having a defined relationship is that you have valid reasons for getting pissed off when your mate ditches you, but in something so new and so undefined, it leaves a lot of grey area for somone to get hurt. I just don't know if I should let it go for fear of seeming psycho if I bring it up again, or do I follow my own advise and let him know I am hurt? I think I should let this particular one slide but I do think that he and I need to sit down and define some ground rules before someone gets hurt. That is the tricky thing about "non relationships" is you might think you are avoiding the "talk" but really you still need to have it to avoid misunderstandings. I also need to do some thinking myself, I have to figure out if I am ready to be another rebound girl, if I am ready to handle another "broken" guy, if I am ready to set my feelings aside to help someone else, if I am ready to get hurt again…
