I want her to be my wife, but is it too late?

My wife and i are alot different. Shes in her early twentys and im in my late twentys. I ride a motorcycle shes into trucks. Shes religous im not. Shes had both of her parents i was placed in foster care. I surf while she plays soccer. We have very few things in common. Shes forgiven me for alot of things, cheating and lying, ive done things to her that were very hurtful. I left her during her pregnancy, was with someone else. She forgave me, we got married. And i can truthfully say i am in love with my wife, shes been the one woman that has shown me kindness(im an asshole in general). Now that im determined to change, shes already moving on, i feel like nothing i do now can prove to her how much i do love her. She doesnt believe me, its my own fault. She asked me for a divorce, and i feel like ****. Should i just give up and move on? Thanks
