Your history with Angie is not the same quality as your history with your wife. You and your wife see each other every day. Your personal quirks have more of an opportunity to become annoying to each other. Angie has been a occasional part of your life. A part that doesn't expect anything from you. A life with Angie will end up being as mundane* as your life with your wife. The problem isn't Angie, the problem is that you are looking away from your wife to see your future. All these years (and all these kids?) with your wife couldn't have been that bad, I think you should find out why you think that there is more happiness elsewhere. (Yes, I know you have been very happy when you were with Angie. As I mentioned above your long-term happiness with Angie is likely to be about the same as your long-term happiness with your wife.) *Mundane- "Every day, not special" Isn't it odd that we think that the parts of our lives that are with us every day are less important that those parts that come and go. What can be relied upon is not valued. Odd.
