Not much to say, just trying to catch up. Although I agree that you have to do what you have to do - for YOU and you alone. Whatever it may be....wherever the path may take you. You seem like a great, thoughtful guy. Your W will be losing a whole lot more than she realizes if you should decide to end things.
In the meantime, keep working on you and enjoy your D while she's still little...they grow up too fast!
