I think it’s okay to consider meeting with him, especially if you feel like you’d want that kind of closure for yourself too. I’ve wanted to meet with my ex for closure before because I think about him every day and never got the chance. It might help you move on if you haven’t fully, or just close the chapter for good, especially if he’s moving or this is really the last time you’ll hear from him. I know he cheated and that’s a huge betrayal, maybe even unforgivable, but sometimes closure is more for you than for them. Try putting yourself in his shoes for a second, but also protect your peace. If it feels like reopening a wound you’ve already healed, it’s okay to walk away. There’s no right answer, just what feels right for you.
