My first post here, but it might be to late for advice

Slowly my relationship with my husband of five years started to die over the past year. There was barely any sex at all, he blamed stress, had testosterone checked, but I had a gut feeling, so I had asked him if he PMO, he got very defensive, and said this just isn't working out, I'm not "in love" with you anymore. This might sound weak but, I apologized for asking him that, and asked for another chance.... Then months later I found a way to check the router, and could see the browsing history, I showed him what I found, he flat out denied it, got defensive, and angry. He had me thinking it was all in my head, I was being paranoid and that every thing was fine... Then months later I coun't take it anymore, I had to know if I was just loosing my mind and being paranoid, or was he really PMO'ing in the bathroom. So I did something I'm not proud of admitting here, I put a hidden camera in the bathroom, and I left it in there for two days, before I checked it... OMG I was sick to my stomach, all I could think about was all the lies, all those times he'd reject me for one excuse or another, how he made me think I was loosing my mind, how he would make me go weeks without sex, but he was having sex everyday. How he had to use ED Rx with me, but didn't have those problems for PMO, how he even went to get his testosterone checked, how did he not understand why his libido was gone ... But I couldn't tell him what I did, because that was a violation of trust he would not forgive. I got rid of the camera, because I didn't want to get caught with it plus I figured I found out what I needed to know. I hit the internet searching for answers, and I found them. Then for some reason I thought if he only knew what I just found out, he would be like oh, wow, I didn't know, and stop. Then we could go back to our happy marriage... But instead he left, hasn't answered my calls or text in 3 days. What I don't understand is how can he be angry with me? I know what he's been doing, yet he's angry at me?? Then he finally text me tonight, and said that I was delusional, and he hasn't PMO in over a year but because of my constant accusations he has lost all the attraction he ever felt for me. Then he said he was filing for divorce, and the only communication he would have with me is over the terms of the divorce, which really sucks because he controls all the money, I don't have access to the accounts, the house and cars are in his name, he makes like 6x's what I do.. I even work for him, he hired me to be an admin on one of his job sites, so now I loose my husband, my home, my car, my job... that's what I meant by a little to late to ask for advise. I probable should of just given up and learned to live with it.
