Has anyone else dealt with their partner being addicted to porn?

I feel so alone. He hasn’t admitted to it, probably because I’m either crying or accusing him right off the bat whenever I talk about it. He has hid his feelings before because he was afraid of hurting me, I’m a sensitive sally. I’m going to try to ask him in a supportive way tonight. My therapist and my mom both are pretty certain that is what our issue is. He follows thousands of girls with onlyfans links who look like BBL versions of me on Instagram. It’s weird. Saw an onlyfans transaction on his bank statement. Our sex life is nonexistent at this point and he takes LONG trips to the bathroom. He says he has zero sex drive and has taken it so far that he got his testosterone checked. But I’m almost certain he’s jerking off in the bathroom everyday. We love each other but god this sucks so much.
