I need to get a grip_insight, Please, HELP

Hi. I'm new here. I think, well, I'm pretty sure my bf is a PA. I keep trying tobcarch him I feel like the PMO police. I feel the need to get up out of bed when he goes to the bathroom at night or early morning to try and catch him. Smelling tissue in the trash. It's like I'm obsessing over this. I found out he was watching 3 months ago. And still didn't think he was MOing to it. Until we hadn't been intimate in a while and I got upset and am thinking well your a man with needs. Then it hit me the internet search, no sex. Many nights of googling. Why isn't he into me. I did bring it up one night (as he hasn't disclosed this to meet yet), but, i had a few cocktails and honestly do remember the conversation.(wrong time I know). I want to bring it up,but, he shuts me out and gets completely silent during confrontation. How do I raise the issue. Also, I saw him stare at a woman recently when he thought ii wasn't looking and it infuriated me. I know he lives me,but, I feel as though he saves himself for the P. He watches As soon as I leave the house sometimes even when I'm in another room. I have seen this in his internet history. I noticed he was googling images of his ex gf(who he found our was an escort and he's cheated with her in the beginning of our relationship). I was so mad i called him and he's like whart are you talking about and I had to divulge the fact that I had his gmail password. Now he searches incognito and he never has give access to his pho be. He says he's a grown man and I don't pay the bill so don't invade his privacy. I'm tired of creeping behind him and wondering what he's doing behind my back. Someone, anyone, Please share insight.
Another thing I can't get out of my head is what he's looking at today, I want to know how loing he takes, I'm curious the faces he makes. I'm just so down over this. I don't know what too do

 

I also forgot to mention, I did see fight the new drug in his searchbhistory once. I'm wondering if he accidentally ran into that while watching P or is it something he looked into himself.

 

Thank you so much. I just don't know how to bring it up. I know he knows that so know now. I just don't want to argue then the sleeping in separate rooms. How should I approach this to him?

 

Should I share those boundaries with him? He has no idea that I an aware of the severity of his addition. I can tell by what he searches every day. He now searches in incognito mode and doesn't allow me access to his phone so, I have no idea what he is doing now? I only have access to YouTube history via gmail. I can tell when he's binging because he looks up in you tube. Also, It amazes me how many searches he goes through in a matter of a minute. Like, why do I care?

Thus is shtterieng my self esteem. I have started by every time I think about It, I try and do something for myself to distract me from the pain

 

We are not married we do have 1 child together and I have a son 4 from previous relationship. I'm sorry I'm not being clear enough. It's just that there is so much bottledinside, I forget to write important details. Please forgive mw

 

Thank you @Kenzi ,@Broken3 @novibe
I appreciate all insight,Please keep it coming. I'm so afraid to approach him about this. There will be seperation sleeping in different rooms and arguing. Not ready for him to shut me out and fap for days
