Well, a very hard question to answer...
If they really are trying to hurt you, well, I believe that friendship with them shouldn't continue anymore... But if (and it can be, that is the way that we sometimes react) it's only the case that it is you only who believe to be hurt, just only because you are feeling sad, disappointed or so (I mean that THEY are not intending to hurt you), well, give them a chance. It is hard, but it is harder to really loose friends, OK? Sorry about my poor english, I may not really express what I would mean
. But take care and cheer up if it's the case!
