My heart is heavy...

August 2018 I got married... The week before I got married I cheated and never told my husband. It ate at me so I was gonna tell him when he got home from work one day but he had already found out. He found out 4 days after the wedding and we separated. Since then I have trying to rebuild my life for our daughter and myself. All I want is my life back. I want my family, my best friend and my husband back. He tells me sometimes he wants to work on it but other times he can't even look at me. I know I hurt him and I know it will take time. It doesn't help that now his family completely hates me and won't even look at me but I dont care. I want him back. What do I do?!? How do show him and prove to him that I am sorry and that he is all I want?
