Only YOU can decide that... On the side of the devils advocate... He DID tell you without prompt, right?? Most of the time, PAs torture SOs with years of sex withholding and gaslighting and trying to hide their addictions and affairs. He just told you. Because? Because. That sounds like a someone who wants to keep you to me. Idk... I wish my SO would have just told me about his affair and addiction. But I can't just Wish upon a star or for his addiction to be different... Some are worse some are different, they all hurt the SO and they all suck. You get the PA you get... That's it. It's about what you do next. If you had discovered instead, do think you would feel differently? Worse? Better? What would be different? How?
