Opinion on me telling my boyfriend I cheated?

I’ve been married for a bit, I want to tell my boyfriend I cheated on him. There was so feelings involved, honestly the other guy could die today and I wouldn’t care. I don’t have a reason as to why I cheated. It’s not that my husband didn’t make me happy, he’s an amazing husband. The best person I know, and I want my life with him. And I have no delusions that telling him could very well mean losing him. At which point, I deserve what I get. But I when I did it I just was checked out of life, and imploding. That’s not an excuse, but I just wanna hear from some guys that. I’ve gotten one male prospective and he told me to just keep it to myself. He also has been cheated on in his marriage. So males? Opinions pls. Girls are welcome to share as well.
