My ex’s getting married next month

It has been a year already since my ex and I decided to cut everything that connects us. We fell out of love after 6 months of living together. I can’t feel any affection anymore, including that spark I felt when we met in a foreign bride social some years ago. Now, I heard the news about him marrying. I know I should be happy for him but a part of me is missing him. I want to make sure if I’m totally done with him, that’s why I plan to see him in a few days from now. Do you think this is a good thing for me to do? I need your thoughts about this.
