What would you do in this situation?

I had an love marriage and I loved my man so much so does he , well I didn’t knw he played so well , he cheated me throughout our relationship which I came to know after marriage , where I saw some picture in his old ph, and I even contacted those girls , some said yes we dated 3 months or some said they were interested and all , I was shocked he even went to trips without telling me , all these things I saw in hi old phone and I came to know about these after marriage, I feel terrible that I know now that I was not only the women he loved ! This thing kill me every day , I feel so bad , such a liar he is ! And how he played with my feelings
