Ex Bullied Me About 'Being FAT' I Can't Believe He's BEGGING For A 2nd Chance!

He used to complain constantly about how I looked! I couldn't stand the humiliation he put me through around my family and friends when he would point out and ask them if they thought I was putting on weight! Lately I've been changing my lifestyle A LOT and now he has been coming back around and literally begging me to forgive him and give him another chance. What should I do? What would you do?

So upset...
