Take a deep breath... if you felt better about unburdening yourself then so be it.
I think the vets on here would tell you to write it out and sit on it for at least 24hr... then think what will this accomplish? Most agree that one heartfelt apology is okay... but to keep apologizing makes you look weak.
Keep working on your changes. They do notice even the smallest ones. My H did. Often times they won't say it... many times they don't trust it... it takes time and what I've learned from having going through this before is that many times they get even more angry. Mostly because if you could do this now you consciously made a choice not to do it before.
