5 of my ex-boyfriends ex girlfriends and I would like to let his current girlfriend know that he cheated on her and has cheated on us in the past, causing alot of heartache and emotional trauma (some of this has gone on for as much as 5 years!). We all agreed that had we known then what we know now, we would have run a mile and think she'd appreciate this information. We have created a facebook group (private) stating the lies etc. which he told and have proof of some of his dirty work. How do we go about telling her without getting sued? Our plan was to invite her to the group which would hopefully open her eyes to the truth. If we stick to pure fact that we can back up and don't throw insults will we be okay or should we just let her find out the hard way... it totally breaks my heart! She is saving up for a flight to come back home (overseas) with him!! If only she knew the true monster he is!
