I think it is wonderful you still can find room to forgive them in all this, that shows real character. I would tell them that you were hurt or dissappointed in them repeating what was told to them in confidence, and leave it at that if you wish to continue your friendship. We learn from times like these who to trust and who not to, but it is so true, once something private of yours is shared it is no longer secret, sad but true. Good luck.
