Similar situation with me..soon found out that my Ex had a new man in her life...from her (supposed) friends. True friends are loyal and trustworthy...and are few!
Like Brucie says Petra...move on...let people think and say what they want..it will all die a death and true friends will stick by you...if you have no friends from then...you didn't have any anyway...just hangers on.
Best wishes, Mike.
