Now your 100% sure there cheating? If your not 100% don't do anything but if you are make him think you 2 are gonna have sex get him into bed and the important thing is you need to handcuff him to something so he's stuck there. Don't tie him since he might be able to get loose. Than just keep playing like its gonna happen than when he's at his most content tell him your friend told you about the two of them and you know what he's been doing. Do not lose your cool you need to remain calm the whole time no matter how mad you want to get dont. He'll probably deny it at first but he should confess.
Now you should prbably get his phone put it to his ear and have him blast this other girl right in front of you,dont talk to her just let him do it. Than get his stuff and pick 2 things at a time that he likes and have him tell you which one to wreck and if he doesn't you'll wreck both. Than when your done with that id take his keys and leave him cuffed and just go somewhere I wouldn't wreck his car in anyway but the whole time your gone he'll be stuck handcuffed their wondering what your doing to his car. dress him up and take pics, the important things to have fun and not go crazy with anger.0THIS IS NOT RELEVANT ANYMORE
