My boyfriend cheated on me. Can people change ?

TLDR I( F27) found out my boyfriend (M32) cheated on me for 6 months with 2 different woman . I never thought he would . We spent 24/7 together after work and always talked on the phone while we were both working . We are a very affectionate couple and intimacy hasn’t been a problem . We play games together with our set up .

 He asked me to move in and always say we love each other . I’ve always communicated if I ever done anything wrong to upset him or what I could do or if he’s ever happy . He always gave me a positive smile . After I found out I was sick to my stomach and didn’t eat for a few days . He admitted his wrong and answered every question I had for a week. He wants me to stay because we have a “ perfect relationship” but wouldn’t blame me if I left because he isn’t a good person . I told him I wanted a restart . He gave me permission to his cameras inside and outside the house. Location and access to his phone and computer . 

I really do love him but I still tend to sometimes hurt thinking if it something I lacked tbh at pushed him to do it ? I’ve never been in a long relationship more than a year so I always think it’s something I did wrong . I feel like he could change to be a better person for me . Am I wrong or a clown for doing this ? Am I wastin
