I just found out my fiance of 3 years is watching other women on his social media. I 20F him 22M

This all happened an hour ago, we had just been intimate, we didn’t have s*x. We made out and I give him head. After that he fell asleep. I had a weird feeling to check his phone so I did and in literally just a second I didn’t even need to scroll I found out he’s been watching a particular women her instagram page, she post her b*tt and other stuff. Anyway so I immediately woke him up confronted him and I also started crying. At first he said “why are you waking me up for this can we talk about it in the morning” when he noticed I was crying he woke up. He didn’t really say much I asked him if he remembered our rule to not watch sexual stuff on the internet and tbh if it was just one post I wouldn’t mind but he went through her WHOLE account. Anyway he said yes. Right now im in a different room I’m so so so mad I can’t stand to be with him, my trust is also broken call me dramatic but we are getting married in two months how can I trust a man? who can’t even control himself on instagram, he probably can’t control himself in real life either. He send me a picture that literally only says “I love you, I know I’m wrong and that what I did is wrong. I shouldn’t have done it I’m sorry. I don’t care!!!! I’m so so so mad, I’ve been asking him for 2 weeks straight now please start sending our wedding invitation to your side of the family and he just won’t do it because he’s “busy” with work but I guess he has enough time to scroll on instagram. We’ve been engaged for 3 years, in our first year together when we weren’t engaged he cheated on me, he still to this day doesn’t call it cheating but he was talking with a girl on TikTok and flirting with her but in his head it doesn’t count because they didn’t meet up and we were only dating for maybe 2 months so I forgave him. Sometimes when I go through his phone I see like one post of a women but honestly I never see much so we’ve never really had a problem like this, I’m so mad and my trust really is broken. I feel so dirty also I regret giving him h*ad, I feel so dumb and stupid. I don’t know what to do.
