"*Knowing that they had no respect for her which was very important to her I foolishly told her what they said.*"

Yeah. . . you really fubared this whole situation. You should have posted something on this sub before trying to do anything, lol.

I think no matter what the truth is (and let's face reality, you may never really know the whole story) this situation is almost 100% unrecoverable.

It's best to just move on . . . a very tough and bitter pill to swallow . . . but this entire incident is a big wake up call from life and the world in general . . . you clearly have a lot more growing up to do . . . work on that, I mean really DO. THE. WORK.

. . . and become a more independent person with better instincts and better vetting skills before entering another serious relationship.
