<p>What a great position to be in! I think you both need to think about what your life goal is for the next 5-10 years and which job helps you get there with the least amount of stress and best quality of job. You probably already have a good idea about which one it is. I’m all for honesty and integrity above reproach, but I wouldn’t worry about the loyalty level as much as college shopping does. IMHO, at your level there is a level of expectation of negotiation. It sounds like you are thinking retirement in a few years, sorry if I got the wrong impression, and when you get to that stage you have to position yourself in the best possible scenario to reach your goals and I think that is more important than loyalty at this stage of the game.</p>
