i'm sorry to hear your heart is broken and that you went back a second time... even though in your heart of hearts you probably knew that nothing would have changed. sometimes we (us women/girls) are really attracted to someone loving us so much but if we're not ready we can't reciprocate. we try, but we can't. this is usually because we're not ready, immature, or whatever else you might want to label it. it is possible for two people to be right for each other but the timing can be completely off. in this way, letting someone go when you don't feel you're getting what you want and need is the best thing to do. you honoured yourself and your needs in the first place by saying "this isn't good enough for me". you never said "you are not good enough for me" so you haven't put anything negative out there. this girl probably tried to love you but wasn't capable for whatever reason but we have to focus on ourselves when things don't work out. as for being "friends" i think your indignation is justified but maybe it could be an energy that could be used for other things. the fact that you question being able to be friends with someone you felt hurt from speaks volumes and you are already telling yourself this is not someone you can afford to have as a friend. friends treat you like the special person you are. raise your standards, and be prepared for nothing less than the best love that could come your way. when you look another girl in the eye and tell her how much she means to you she will see you and match you. walk bravely and with awareness into your next relationship and always trust yourself. i don't believe there are huge mistakes in love, i believe we learn a little more about ourselves in every experience and that is always good. keep going and gently drop her off your christmas card list. then there is space for a new love who will appear when the coast is clear.
