Help me!!! How to respond to confessions

“I looked at content this morning idk why I did, I looked up Reddit then looked up celebrity and “stumbled” across it. I’m sorry ik what I was doing when I was doing it and I know I was wrong. I’m really sorry and I hope me telling you means something like that I’m actually wanting to change”

This is half the text, I left out the extra apologies and just kept what’s relevant. He’s never come to me and confessed use before. He disclosed to me a year ago and on and off white knuckled since then. This week he has been really trying - but with only outside resource being a weekly SA group. I know he needs a CSAT, they’re a limited (expensive) resource here but it’s on the list nonetheless.

I suspected as soon as I woke up this morning. He gets up much earlier than I do, but usually wakes me up and says good morning, leaves to get ready, then says goodbye before he leaves. He took his phone when he went to the shower so step 1 was violating that boundary and I noticed him do it. However - him texting me to confess (which he said he knew was a weak move vs telling me in person) is a new step.

I just told him we can talk when he gets home, but I want my thoughts gathered before then and the conversation to be productive. I want to ask if he searched and looked or if he continued on to masturbate/orgasm. I don’t know what else to ask or what I should say. I know I can’t do the work to change for him but I still want to point in the right direction. He knew what he was doing every step of acting out - so how do they even change if when it comes down to it they choose to take every wrong step anyways?
