Boys problems

So I just recently broke up with my boyfriend , we were together for 11 months but been off / on for about 1 year and half . Bitbitbfelt like a lifetime 😰🤔
I loved him and he loved me (so he said ) 
And I broke up I whim as he told me he kissed another woman !!  Few months into the relationship 
But he was so drunk that he can't remember if that happen . 😡
He only knows as she told him !! 
But then it happened again with the same woman and he was still pissed out his head !! 
And I don't know what to do 
I'm heart broken but I love him 
And he still wants another chance 😣🤔
Help me fellow ladies !!!
