This will make him think that you don't care about him anymore and quickly found someone new. You might text him, "Thanks for taking me out last night. Can't wait to see you again." Then, send, "Oops, wrong number. Deleting your contact now." While you should never post private photos of an ex, you can get away with posting unflattering photos. Share the photo on your social media page or have a friend post it. As another option, print out the photo or turn it into a poster, then hang it up around your ex's neighborhood or at their favorite hangouts. For instance, you might use a photo of your ex doing something stupid or one of them on a bad hair day. Don't post a photo of your ex in the nude or partially dressed for any reason. Tell your ex that you need to come over to retrieve something you left there when you were dating. While you're there, hide an item that you know he loves, like his TV remote, his favorite video game, or pieces from a Lego set that he owns. This will drive him crazy until he finds the hidden item. Don't take anything of his because that's stealing. When you hide the item, make sure that it won't get damaged. For instance, it's okay to tuck the remote between the couch cushions. However, it's not okay to put it in the back of the toilet where it will get waterlogged. Put the item somewhere he'll find it eventually. As an example, you might put his bottle opener in the wrong kitchen drawer but not in his air conditioning vent. If he's already seeing someone, it's probably very painful for you, especially if he cheated with this person. Try not to take things out on the new partner because they may not have known about you. However, it's okay to let them know that your ex may be bad news. Send them a message via email, social media, or text that explains what happened in your relationship. Create a fake profile on social media or use a dummy email address. If you want to send a text, try an app that lets you send a text from a fake number. You could say, "I heard that you're dating Liam. I thought you should know that he was already in a relationship when he started seeing you. He cheated on his ex, and he lied to her constantly. I'd be cautious with him if I were you." This is a great way to get back at him because you don't have to do anything. After he hurt you, it may have felt like he got away with treating you wrong. However, his actions will eventually catch up to him. Just sit back and watch him deal with the aftermath of his bad behavior. For instance, right now he might seem on top of the world with the person he left you for. However, people will recognize that he's a cheater, and that'll hurt his reputation. Additionally, this new relationship started off in a bad place, so he and his new partner might develop trust issues. Think about those consequences whenever you feel upset about what happened.
