just tell them you know they are lying and then you can give them a chance to explain if you want

after i catch people out lying i never trust them again so they by definition stop being my friends:bounce_fl:bounce_fl:bounce_fl

i wouldnt have anything much to do with them again – you dont need friends like that:you_crazy:you_crazy:you_crazy

and they are the losers in this situation – they are missing out on a very special person and they were too stupid to see a treasure when they meet one:you_crazy

you dont need to do anything to people like that for revenge – just enjoy your life and that will be enough – their karma will get them far better than anything you could do to them
what goes around definetely comes around – i have seen it many times
