UPDATE! lying Husband..what should I do!?

I know a lot of women are okay with Porn. Whatever that's fine. I however am not one of those women. I told my husband that I considered it cheating. He lied to me for 6 months until I finally caught him. We agreed it wouldn't happen again. I finally started trusting him again and found it again a month later. I again forgive him and when we got into a fight he "out of spite" did it again. He even told me if he found porn on my phone he would leave me because he considers it cheating and I should wait for him to get home. Now I wouldn't be so upset if he one didn't lie to me (I even asked and told him I wouldn't leave or judge him and he swore up and down he never did) and if it was actual porn. He was every single day looking, 14 times a day right across from me on the couch, before we had sex and when I'm literally laying on his chest at night, looking at pictures of naked women on Reddit, which he could easily message these women, and then receiving them from women on this game he played online. This is something that's a deal breaker for me. He keeps telling me he will never do it again..but I don't believe him? What should I do?.
Update: so some of you said to get over it. No, porn is not something I condone. I also do whatever he asks. I even put out 3-5 times a day, made sure if he was too tired that he either had pictures of me (which his comment was they are just pictures of your boobs, or butt and that's all he was looking at was pictures of asses and tits) or I'd give him head or let him jerk off on my face or boobs. I've put out, I told him I'd do anything he'd like. I'm not ugly, I've got a very nice body. We have no problems in our marriage for him to even turn to it or lie to me... 
Update2: thank you for all the kind words. And to the women who had nothing kind to say, thank you aswell. Porn is something I will never be okay with, he won't do therapy because he swears if there was a problem it's gone. I still am at a loss for what to do. I don't know if I should trust him on last time? I've never done anything wrong to him to deserve this. He's made me feel so low about myself, he always told me my changing body was disgusting (I just had our daughter a month ago) and that because my nipples had darken they were gross...while doing all he was doing. I was a very pretty pregnant person, never gained weight anywhere besides my belly. I was really healthy and thin before hand and he'd call me fat...also he lies about little things too like if he had anything drink or if he smoked in the car. I love him and want to work it out but I don't think he's ever going to change 😢
