If your asking on an easy way out of a 16 year relationship with kids...there is no easy way out honestly. It will be hard to do it but I would not advise using "I don;t love you anymore" or "I've been cheating on you for all of this time" as your excuse...If you are not getting along then maybe it's best to go that route and let your partner know that you can't do it anymore but 100% want to do your best to keep the friendship there and be with your children. I hope it all works out for you.

I'm not sure what you mean. Are you married and having an affair with someone else?

Be honest, and realize that your family may not stay together. A 16 year long affair isn't something that everyone can get over.

But perhaps the other person knows? It's harder to hide than you think.... I'd just be honest and see what happens.
