This has been the extent of our communications. So to jump from this to making sincere amends will require some real finesse.
Why?
I would take a sincere apology even after a hundred years of no communication. It would help me heal and feel validated. I don't agree that amends are only something you do for you. I think sincere amends are a gift you give to someone you've treated badly. Hopefully, you both feel better after, but it's not about you. It's about putting things right in the best way you're able.
