The condemnation and the anger is the shame talking. You can't heal that Kyrie, only he can.
You are doing the very best you can at this moment. You predict he is going to get mad, so be it, put your spew jacket on, he needs to vent and unfortunately your the target.
At this stage I don't think there is anything you could text him that would soothe him. Just take your self esteem and ego and step back from what he is saying just at the moment.
The other thing Kyrie and I mean this respectfully you are completely absorbed in everything H is doing and not doing. Take a moment while he is away and focus on you. Get a plan together. Stop living moment to moment to each conversation and text with H and start working on a real plan.
Personally I would be talking to a therapist about my worries that my H porn use is potentially going to place my daughter's sexual safety at risk.
That I don't know how to raise how concerned I am about everything because H, distracts and stonewalls with emotional manipulation and anger.
That I don't know how to create space for us to get perspective. I don't know how to say that I can't live like this anymore, but I want to keep our marriage, but I don't want this.
That I don't know how to say I want talk through issues within our marriage, but with someone else who can guide and give us perspective.
Kyrie in the country where I live adults watching/accessing porn that involves under age children/young people is illegal, and involves a social worker like me visiting and discussing safety planning with parents. I don't know what you have seen H accessing but, if your know if places children and young people at risk. It needs to be addressed.
Kyrie take a couple of steps back from everything and talk to Cristy please. Get the help you need.
You need a plan for you Kyrie, otherwise all this keeps going.
