My ex-boyfriend said that he would go to Shanghai thousands of miles away tomorrow and wanted to have dinner with me before he left. Should I go?

My ex-boyfriend said he would go to Shanghai thousands of miles away tomorrow and wanted to invite you to dinner when he left. That's up to you. If you have completely put him down, have no feelings for him, and have become ordinary friends, you can go to have a meal and say goodbye. If you haven't let him go completely, then don't go and rekindle the pain. Too many memories will only make you reluctant to let go, not to mention that he will stay away from you, and you can't be together.
