I (19F) caught my boyfriend (20M) sending nudes to someone, can i save the relationship?

Me and my Boyfriend have been together for 2 years, things have been weird for the past couple of months. He’s been having performance anxiety in the bedroom struggling to stay hard etc which is partly my fault (he has told me my frustration from him not finishing/staying hard makes it worse which i am actively working on).

I suspected that he had a porn addiction that he was not admitting to. last night i did something stupid and looked through his phone. I’m aware that this is a complete invasion or privacy and there is no excuse, i had a the feeling something was off and the thoughts got so loud that i decided to look while he was sleeping for peace of mind

Instead i found out that he had sent a nude to some random person he found on reddit around 2 months ago, i believe the pictures were sent through telegram. I saw that he was asking chatgpt what to do because i think the person was trying to blackmail him as the photo included his face.

I confronted him about it last night, he admitted that he did it and said that he had struggled with a porn addiction during lockdown and it had came back at the start of the year and that he was really struggling.

i asked him why he sent the nude picture and he didn’t give me an explanation that made sense, something along the lines of “to me she wasn’t real it was just a porn thing in my head”. (if anyone can understand that please explain)

I’m really hurt right now, i love him so much and really don’t want to lose him but i don’t know if there is any way to save the relationship, i just feel now that there is more things that he is hiding from me. i don’t know if i can rebuild the trust with him after this.
