porn addictions

i wanted to reach out because just about a week ago i found out my boyfriend had an addiction to porn. it was obviously a shock to me and it was painful to see the stuff i saw but ultimately i decided to stay with him. he was very apologetic and removed everything from his phone even let me put a safe search on his phone so it seems like he's trying to be better but it's still hard for me to stop thinking about it and comparing myself to those women. we’re both somewhat religious but after i found out he’s been praying with me and by himself for God’s help and forgiveness. he's owned up to everything and says he feels awful but i just don't know if it's wrong for me to still be with him after what he's done. we've only been together for about a year and a half and he said it just started a few months ago so i just think to myself what did i do wrong. i knew something was off for the longest time and it made me very insecure but i never found anything on his phone until i found an ipad under his bed with everything. i want to forgive him because he’s always been good to me until this. i just don’t know what to do, pls help.
