What is worse? Never seeing the ex you love again or seeing them hugging them knowing you can't be together?

My ex and I talked after being separated for years, he said that he wishes we will meet again, and that he wishes he could hug me.. I also felt that I miss him incredibly and that for a moment my happiness that has been gone for years was returned; however, we can not be together because a lot has changed and we will hurt other people. Both options are incredibly hurtful, never ever meeting again, also seeing each other and hurting again cause we can't be together. Which is worse in your opinion? What would you do? Knowing we stayed no contact for years, thought we have moved on, then boom all that was said exactly after 8 years of separation.
