What makes you sure that your staying for your kids was worth it? Pretend you had divorced, (I hope you don't, your sitch seems to need sex alot, but I kinda feel you have a real opportunity by doing things a bit differently), you'd likely have remarried in your 40s before menopause and all that stuff. 10 years later, it might be a little more challenging (or easier?) Was her love/your love enough for the last 10 years to satisfy your non-physical needs?
