Just as sodium pentathol (sp? -- "truth serum"), or even alcohol for that matter, doesn't make you say things you don't MEAN, it just makes them more likely to COME OUT . . .
So do the expressed "unmet emotional needs" of a fogged-out wayward spouse. I've found, thru studying thousands of these situations, that even though the DATES might be b.s. ("re-writing and back-dating of marital history), the complaints themselves are usually VERY REAL, or at least CONTAIN truthful elements to them. A betrayed spouse ignores them to their detriment, Kimmie Lee.
Yes, deal with the affair first, if there is one, and don't agree with b.s. re-writing of marital history IF it's b.s. But then you'd damned well better also have a plan for working on yourself, and on your partner's unmet needs and marital complaints if you decide to take them back.
