Advice please

The last month or so the guy I’m dating has become very hurtful time after time by being smart mouth, his tone, etc. he lied to me around a month ago basically about looking at something he promised he wouldn’t ever then deleted it but told me about it AFTER I asked. Well I’ve had the flu the past week along with him & my parents so we’ve all been piled up in the house.. I haven’t been checking his phone much cause I was trying to trust him & believe things he was telling me. To try to get to the point, I got his phone Thursday to download McDonald’s app & just so happened to pull up like 5 pics of porn on the search on his main phone part. Come to find out he looked at it around 2 weeks ago supposedly 2-3 days before deleting it “because he didn’t know where our relationship was going” because I had been distant & short with him (after explaining numerous times to him I felt unwanted & unloved from the way he had become ill tempered, aggressive, & mean towards me). He knows from the beginning how I feel about porn while in a relationship & he knows how I viewed that stuff so hurtful & not right that I didn’t like it & explained several times from the start what I had been through & how it made me feel. He even went as far as promising on our relationship ending that he didn’t look at it when I asked him weeks ago. I am almost 29 & have honestly been through so much from guys in the past all while just wanting to be truly loved & it last & have God in the center of it. Im at a loss for words & dont know what to do anymore. I love him but I feel if he’s already doing this so soon into our relationship that it won’t change & he’ll just go back to it anytime “things are unsure” or we’re not on great terms.
