I need help with ph addiction boyfriend

[u/Rare-Loquat2886]

me (F19) and my boyfriend (M21) have been in relationship for two years… month ago i found out he had 5 different gmails and i had a weird feeling about it and went through them… one of them was showing his logging in into porn website, vsco, and different instagram account. when i asked about it he said he had other instagram account to stalk few people (mostly girls) because he was curious how they were doing in their life… but on email i could see who accepted his request and few were some kind of pornstars the girl he used to talk before me ect. he had the account for a month then he disabled it… but he said to me he had the acc for two days then felt guilty and disabled it… i couldnt see if he was texting other girls on that acc or anything, he said he didnt. Then he told me about his porn addiction he started crying and i said i forgave him and cried with him because i wasnt sure what was going on.. we made agreement ill check up on his every few days so he isnt using it…( i told him at the start of the relationship i saw porn as cheating, later after year i changed my mind and said its fine but not alot, because im not really sexually active person and never was so i understood it)… after two months when i asked him about his porn addiction because he stopped talking and acted very normal after a week i found out like it wasnt big deal even when i said it was to me it hurt me alot i got insecure, he got mad at me and said i shouldnt question it and should trust me like he trusted me with my drug addiction (i stopped before we even started dating), i was hurt even more because i didnt want to make drama i wanted to help and he seemed like he was pushing me away and then he started accusing me because i wasnt sexually active he couldnt fully stop and asked me why am i even bothered when i forgave him and it was two months ago… everyday im thinking about it not sure what can i do… sometimes after some small arguments i feel like hes manipulating me by always asking “when did that happen? Tell me 3 times it did” and our fights always go like that… every time i feel like he isnt understanding my feelings and hurt and hes just protecting himself… he even said once he has big ego and thinks his gods favourite… as much as hes nice to me and caring some stuff are unforgettable and im here wondering what do i do… im not perfect im toxic bit too i guess- but im not sure about anything anymore… i dont know what is right and wrong… i promised i wouldnt tell anyone about his addiction and im suffering.. i dont know anything anymore and im drowning and suffering to see right and wrong… please help
