It's probably just a way to deflect from feeling guilty. My H wants to be friends too, but I am doing a much better job at that than he is. He can't seem to let go of the resentment he has for me. Maybe there's some guilt to.
If your H, after everything he's put you through, doesn't know what you mean by "how you've treated me", I really don't think a text message will be enough to explain it.
