Have you read the "Boundaries in Marriage" book? That really helped me understand the concept. The "sticking around for the kids" issue can run both ways. What are you teaching them about healthy loving relationships? About standing up for your integrity? Are they going to thank you in 15 years for making yourself miserable on account of them? It's not that you have to walk out the door tomorrow. It's more, "I will not live forever in a sexless/loveless marriage." No definite walk-out date is given...just the promise that you won't be around forever if she's not willing to work on it.
