What is love?

I'm not sure where to post this. But I recently found out my bf has been lying to me for the last 3 years about looking at models and gorgeous women online. I would try to causually bring it up every once in a while when my gut was telling me something was off, I trusted him though so i was hoping we could chat about it (bcuz I knew he was looking, I'd accidentally walked in a couple diff times) i wanted to feel more comfortable about it and he would always turn into a fight. Into him freaking out about not being the type to look and say oh fine ill never go on my phone you dont trust me. Finally about a month ago I confronted him about it and said show me your phone history and I had never been so insecure until I saw how much he was looking. Like looking at individual pages and going on there daily. And by daily I mean anytime he got a chance. I am heartbroken that he lied for these years and the extent of his looking. I feel like I wasnt naive and know that people still have eyes. But I dont know how him and I are a team anymore. Has anyone else been in something similar ?
