Dumper and Dumpee

This is for my own curiosity. I was recently the dumper and as always , I am regretting my choices as I spend my days thinking about them. But now I want to ask this question

your answers can be a simple yes or no , if you feel comfortable enough to share more by all means. I also understand this is all circumstantial and you guys do have your own lives

Dumpers: do you really regret your decision on dumping someone you loved ?

Dumpees: would you forgive them for their decision at all ? Or would you not give any energy to it ?

P.S. I do understand breakups are never easy , so if this post is too much or causes a lot of emotions, I will take it down and respect those that are currently healing and getting through it ! Have a great day :) !
