Need help

I 29 male and my wife 28 female have been married for about a year and a half during that time I neglected to tell her about substantial things that happened in my past regarding legal issues recently we had been arguing a lot to the point that the police got called. I ended up going to jail and she found out about my prior convictions. She now wants to get an annulment of our marriage. I still love her dearly and want to pitch the idea of starting all the way over from Square one we were long distance for approximately two years one of which we were technically married during that time I cheated on her. I love her more than anything on this earth and will do anything to make things right and try to fix this marriage or what is left of it I need advice on how to do this as she took a restraining order out on me and has made her intentions clear.

Tl;dr how do I show my wife I’m willing to do anything to salvage our marriage no matter how much time or effort it takes to prove that I’m the man she thought I was.
