much how can I get him back after what i have done?

me and my husband separated , it was all my fault he felt numb towards me because the scars are so deep he says. i know that we can find a way around it .i accused him of cheating on me for many years .I’m a jealous and insecure woman .the problem wasn’t him but me . i don’t know if there is any fight left in him this time because he already moved out. I’m emotional wrecked since i have realized what i have done i cry all the time and randomly break done i am trying to be strong but he is the best thing that has ever happened to me i really appreciate what he was doing as a husband in the house i love him and i miss him so much how can I get him back after what i have done?
