<human>: I have a boyfriend who I mean the world to. He is absolutely in love with me, would do anything for me and our 3 yr son. Two days ago, I admitted to cheating on him with a friend two years ago. I did it because I did not see a future with him at the moment and tried to break up numerous time before (and twice after) I cheated but he wouldn't allow it. Our six year anniversary is in a week.

I decided to tell him now because I realized I am madly in love and we cannot have the future for our family we often talk about with a secret like that. I wanted to give him the opportunity to know what I did and decide to leave me or not. I knew telling him would shatter his world and it did. He despises whores and I am now considered one. I have tainted myself, I was THE perfect woman. He has never even masturbated with the thought of another person. He will no longer kiss me. He told me the past two years have been a lie and he no longer feels anything; he is dead inside. 

However, he still loves me. We are both aware that I will never be looked at the same but he says he is willing to work on us. I am eternally sorry for what I did and eternally grateful for another chance. 

Obviously, he doesnt trust me anymore and has every right not to but I will never do it again. Our question how am I suppose to regain his trust? Make sure that I won't lie or cheat again? I suggested putting a tracking device on me but that wouldn't work.

Can you condense the text into three sentences or less?
