Hello M

That is a big development.

Continue with the path. H has quite a tangled mess to unravel and straighten away. That will not happen overnight; a long road as you say.

Still, an admission of regret, and how the grass wasn’t greener. Positive steps indeed.

Keep on your path. Keep living your life. Let him catch up. And see what his actions tell you.

Feelings are fleeting.
Be better, not bitter.
Love the person, forgive the sin.
