Thank you for the replies.
Initially I thought it was primarily to do with me - but I think on second thought - it is more to do with her... Perhaps (like you guys mentioned) this was her attempt to look after herself and in so doing - she had to make the decision to stop communicating with me because she knew it would be hard for me to make that decision...
Still hurts though. I really liked her - in a companionship sort of way.
Interestingly enough - I graduated high school a decade ago and one of the group members was in my grade... She and I communicate a bit - but I set boundaries with her because I sense that she is VERY clingy. I do it because I don't want to hurt her... In retrospect - perhaps this is why this other girl did the same to me... Though it is very hard to swallow that pill.
Thanks
