My WH went through something similar about a year after DDay 6, when we had DDay 7. Long story.
Anyway.
He was at his lowest. The trickle truth finally stopped. Finally.
He hit bottom with porn and alcohol addictions. He was finally able to speak aloud about all of it - and it came out in hours of crying, talking, and a story of his parents’ divorce, his father’s affair (and marriage to the AP, divorce, remarriage to his mother, it’s crazy).
I was also at a low. WH didn’t want to do therapy. It was a sticking point - he was reluctant to go for many reasons, but his shame was the biggest. We got past that. I felt alone on the recovery road. He finally joined me in a way that felt more supportive, where HE was also visibly healing himself, which has made a huge difference.
I was worried, too, that anything I did or said would drag us backward. But I kept emphasizing that the ONLY way forward was together, armed with radical truth.
If we avoided the truth, we would never get anywhere. And the truth included my pain, his history, the fears we both have, and the fact that we are on this uncertain path of trying to recover from a nuclear bomb exploding in our relationship.
We talk more calmly now than we did before. It gets easier, but we still both cry at times.
I’m happy to hear he is trying, and being honest about why he was being such a jerk before. Addiction is such a terrible disease.
Sending prayers.
