So my ex and I have known each other for like 3 years. We dated other people after breaking up . He moved on 1 week after and I moved on 4 months after. He messaged me a couple of months ago and we started talking again since I thought he was single. So we hooked up on Nov 7 and on November 28 his ex which I thought weren’t together posted a picture of him on instagram saying I’m thankful for you.. I sent her a picture of when we hung out and let her know the bullshit he did. He played both of us. I did my job and this dumb bitch stayed with his cheating ass. I know he probably made some stupid lie but she will soon realize he isn’t worth shit. I wasted so much time on him. I regret it. I got my place, work, go to school. And he still lives with his mom. His karma is coming.
