Was I morally correct in asking my (now) ex-wife to delay the divorce which she had initiated, in order to retain her much needed health insurance under my employer, until she had obtained such on her own? Or was she correct in her assertion that it would have been morally incorrect for her remain married to me, regardless of her health needs, due to the example shown to our children when she was meeting and dating others?
