My boyfriend slept with someone before we were official

Me and my boyfriend have been exclusive for just over two months now. We were seeing eachother for atleast a few months. He told me he liked me about a year prior but I told him no as I was currently in a 4 year relationship that I had been in since I was 15 (I am now 20) We remained friends, until something happened with my ex boyfriend. He was very abusive and controlling to me and had been for 2-3 years. Long story short, he hit me with a car & I sustained injury’s so bad I couldn’t walk or sleep & bathe comfortably for the best part of 2 months. When this happened, my current boyfriend (who I was friends with at the time) was there for my every need more than any of my friends were. I don’t think I would still be here if it wasn’t for him and one other family friend that helped me through it, although I did not take advantage of his help, I opened up to him about what had happened to me. I knew he still had feelings for me and told him I’d like to remain friends for the time being and take things very very slow. He agreed to this. We were always very close and got along very well, one day there was just this spark and we started seeing eachother properly. Now to the important part, around 3 week before we became official I found out he has been sleeping with another girl. Despite denying this and lying about it to me when I asked stating they were “just best friends” which I believed as they had been for years. When I confronted him about this he denied it with a very sad and concerned face until I showed him evidence that I knew. He then admitted it and started apologising stating he never told me as he didn’t want to loose me. He told me times where he wanted to tell me but never did as he knew I would of walked away. He told me he never had feelings for the girl and had no idea why it happened and told me it was a genuine mistake and it started when they were drunk one night. I also asked him that if I didn’t find out would he have told me? He said no as per the same reasons I mentioned earlier. My only concern is that it crosses over when we were taking things seriously. Although it did stop a few days after. (E.g. my sisters birthday might out, he picked us up from Chester which is around 45 mins from where we live. Then came out round the clubs in our local town, we then carried on the party back to my house. A few people stayed over but I wanted to be with him so me and him alone ended up going back to his (which conveniently is around a 3 minute walk from mine). I wanted to stay the night but when we got there he immediately just seemed like he wanted to have sex, which I’m guessing because he was drunk and attracted to me. I told him I didn’t feel comfortable and he walked me home. He ended ip meeting a few of his friends which were still out and partied on well into the next day. That night he had her round to his house) He used to tell said girl how much he liked me and used to get excited telling her that he was seeing me. He always told her it was just friends and he didn’t like her in that way and she agreed but as a girl, you kind of always know how another girl feels. A few of her friends told me on a night out that she was obsessed with him, she seemed to be jealous of how he felt towards me & they told her from the start not to go there and they indicated she knew she what was getting into from the beginning as he told her he didn’t like her like that. Not to be rude, as I would admit if she was but she’s not very attractive. Or very conveniently attractive. We are complete opposites. I know he loves me, he still gets upset about it now. A few days ago, when we were in bed falling asleep he cried to me about it and told me he hates himself for what he did. I’m trying to move past it and I’m doing well but sometimes it just creeps back in my mind. I can honestly see a long and happy future with him. I just don’t know how to move past this. I’m not sure whether it’s because he is the only person I ever trusted not to hurt me. He puts in so much effort to the relationship and continues to show me what real love is every single day. He treats me like a princess and makes me extremely happy. I just need a strangers opinion on this as my friends are useless.
