My husband is leaving me because of my sexual past before we met

Today is our 7th anniversary. Our daughter will be 2 soon. Today he told me that there is no path forward for us unless I can admit that sleeping with other people before we met was morally wrong. I dont believe it was morally wrong but i dont know if im being too stubborn. Should i just tell him what he wants to hear so our family can stay together?

Ive told him that that part of my life is completely behind me, I've completely moved on and that he is the only one i want for the rest of my life. But this isnt enough to mitigate the hurt he feels. He needs me to share the same religious beliefs on this as him and i just dont, part of me wishes i did. He wasn't religious when we met and while he showed some discomfort with my past when we first started dating i though we had moved past it.

My whole life revolves around my daughter and i love that but i dont have any friends or community or even coworkers to talk to. I feel so alone and so broken and so dirty. My little family is all i have, my whole world
