I want to ask my ex-husband if I could pay for he and his date's meal because I felt guilty for how ugly our divorce was
Is their something good about your divorce that you could tell them?
No, we both wanted revenge on eachother.
It is good to want to help others after you hurt them. You should not expect him to feel the same way as you.
I don't care how he feels I just want to do my part.
Well I'm glad that you are being so civil about this. It is good to try and make up for a past problem. Be respectful in case he does not want you to pay for anything.
