Is this normal?

So my husband (30M) and I (30F) have been married for 7 months now and like many people have our own pasts before we met. For me I used to have an OF with no nudity content. I did that in my early 20s before me and him ever met and stopped pretty shortly after and put that part of my life behind me. I never told my husband about that part of my life though not because it was a secret but it just never came up in a topic between us which was a mistake on my behalf since he found afterwards. Its hit him pretty hard about finding that out which I do understand but we have been trying to work on things between us and have talked about marriage counselling aswell.

Things have happened since than that have not sat well with me though. Of course my husband asked me what content I made on there and I told him because he found old screenshot with chat with a OF fan that I had no idea about (for context he went on my phone and found that screenshot which is how he found out I used to have an OF and also I have a bad habit of not deleting anything off my phone after its saved on). He doesn’t want to believe me what I tell him about the content that was on my OF and I’ve tried to see if my account can be restored since it was deleted many years ago so I can prove to him.

He has been obsessing about this for a while now and it escalated to the point where he had written the name of the person in the screenshot that I had a conversation with on my OF. He looked the person up on social media and thought he found the right person and started asking a random stranger about me and a whole bunch of random questions including what content I posted on there. He says the person ended up blocking him and the messages have disappeared but I’m not sure of that.

My thing is is this normal behavior? Has our marriage gotten to the point of no return? And can a marriage counselling even fix this mess at this present moment?

TL;DR me and mt husband are having issues in our marriage with trust and I don’t know if its any way of coming back
