cheatinng and telling

I cheated on my boyfriend over the past weekend and Mustard up the courage to tell him about it. It went about as well as anyone would think. He's obviously hurt and angry and I'm pretty sure we're over (even though he didn't flat out say it) I feel awful. 
I know I was wrong and I cheated but I do have feelings as well and not only have I devestated him with a cheap lapse in judgement I've devestated myself. 
.....
I guess what I am really asking is now that I have gotten my self in the situation of losing the man who has been such a huge part of my life for so many years.
How to I take a step forward I haven't been single in 6 years this is extremely hard how do I transition.
I don't want to ask him to stay after what I've done.

PLEASE NO JUDGING COMMENTS I TAKE FULL RESPONSIBILITY I JUST WANT TO KNOW HOW TO MOVE PAST IT.
