Hello & welcome
It sounds like you done good to me, lol.
You're open & honest with both men--bonus points. You didn't start it out as an affair then try to go poly after the affair was discovered--bonus points. You stopped communicating with #2 after telling hubby about it. Yeah, you're going in the right direction. Just give hubby time to wrap his brain around it and ask any questions he has & give #2 the time he needs to come to terms with openly sharing you.
