Needing Advice on Porn

So my boyfriend and I have been dating for roughly two years, and been friends for three. He started to pursue me when I was single getting over a break up, and still remained a friend even when I temporarily got a boyfriend (who was an asshole).

So he knew a lot of the things that hurt me from that past relationship, one of which, I was repeatedly cheated on & my ex repeatedly saw other women behind my back.

Going into this new relationship with my current boyfriend we made a couple sex videos and I told him he should use them whenever I’m not around.

A couple weeks ago-I caught him using porn of like, red heads (I’m a brunette) and I told him I was deeply hurt and upset about it because why did I give him so much material. My ego was hurt and I made him delete all the videos and pictures of me since I said he didn’t need them or want them but I asked he stop looking at porn and he said he would.

Then a couple days ago I noticed he was looking at porn again and when I confronted him about it, he lied and tried to deny it until I showed him his search history and then he gave in, I’m now hurt again he lied to me about it and now I’m very suspicious of everything. He works a lot of events and is out a lot sometimes until 9 pm and he works with younger women and in my opinion pretty women, now I’m so paranoid and hurt I can’t have sex with him without crying and I just don’t believe anything he says. Please help. (I’m 23 & he’s younger than me by a year)
