It sounds like you're not valuing yourself as much as you ought to. Yes, the OW is younger, healthier, whatever, but you must have a lot more maturity, wisdom, inner-beauty, and strenght than she could ever offer. Your husband will definitely have mood swings as long as there's contact with the OW. You really can't help that. I think you just need to improve yourself and not worry about competing with OW. She'll probably find someone younger and more physically attractive than your H and move on anyhow. Also, if your H comes back, don't consider yourself the 2nd choice, consider it him coming to his senses, b/c I don't think anyone would return to a spouse they left unless they really wanted them back.
