I'm thinking about leaving my husband with a p/a

Like the title says my husband has a p/a we've been together for almost 3 years married for almost 1 he's 26 and has had an addiction since he was 10 I've tried my hardest to be supportive and helpful and patient.

I do my best as his partner to not judge and to not take it personally because I know it's not about me but it's been eating at me and I'm starting to resent him for it. I'm not his typical type and his p/a shows it. All I want is him I've always wanted him but I just don't know if I can stay and know he does something that tears me up inside and hurts my image of myself and whether or not I'm good enough or if he actually wants me.

I just don't know if it's wrong for me to think about this and feel this way and I don't know what I'm actually going to do I honestly just needed this off my chest and needed advice

UPDATE: because it seems to have gotten worse he's now lying to me about watching porn and seems to be roleplaying with AI on a website and refuses to actually come clean and stop lying to me. I tried to bring it up to him once the past few days and it got me nowhere except in a huge fight with him which is solidifying my reasoning for wanting to leave him...
