Sorry you are here but it will help. We are all here for the same reasons. Start by giving him time to think through what he has done. Give yourself time to think about what has happened and what you want to see happen next. Set some short term goals.
No, your behavior is not backfiring - the techniques in DB take time and do not work over night.
Why does does he think it is better? H seems to tell the truth - what has he been up to that he isn't telling you? What have you noticed lately that you ignored in his behavior? When did the changes start?
Sounds like he needs a break - don't we all at some point? I know its hard on you and your D8. Read through other people's postings to learn more. Re-read the book. There's more advise than just acting ok. Work on the goals. Short term ones that can be resolved in a few weeks that way you will see the small changes. But buckle your seat belt and be patient. Your love will go a long way if you can be patient.

any other help just ask. will check in tommorrow.
