Most Helpful Girl
You're not responsible for his happiness. He probably does have regrets now because the way he treated you led to the divorce, but it's too late. This ship has sailed. I understand you don't want him to be unhappy, but when he abused you, he didn't care about your happiness. You rightly say that you don't want to sacrifice your life again, so make sure he doesn't suck you back in. Try to remain as formal as polite as possible during these meetings you have to have with him, but keep the distance.
