Broken relationship

I was dating my last boyfriend for almost over a year , may not seem long but it was my longest . I cared & loved him . He " felt the same " and I believed him at first . A few months after we started dating I started hearing about him and other females but I wanted to ask him first before I assumed and he told me it wasn't true .. of course I believed him but then I asked the girl ( who was believed to be having sex with him ) if it was true and well it was .. but I forgave him then it happened a few times again . Females claim they would have been done if they were me but its not true , especially if you loved him as much as I loved mines . He messed up and as much as he claimed it would never happen again a deep feeling in my heart knew that it would . So I ended things and even had gotten a new boyfriend but no matter what I couldn't stop thinking about my old one .. something about him and the way I feel so free and comfortable around him makes me wanna stay close . He feel likes home . We went on a date again a few days ago .. but ever since we haven't really talked . He kept saying how he really wants to be with me again but I kept making obvious that I didn't trust or believe him anymore . In a way I kind of blame myself for the way we are now . I should've been more understanding that he's a guy who has sexual needs .. and maybe the problem was that I didn't give it up easy and that I never wanted to really do it as much. Idk .. should I give us another chance ? Or wait for the next to come ?
