and throughout all this time, you never took Gucci's advice to start dating? You seriously had nothing to lose and all to gain, it may have been the kick in the butt for your wife to realize what she's losing when she hears you're dating.
Dating means you're moving on, it's becoming your decision now, not hers.
Someone else dating you increases your value in her perception, currently she's leaving you, you have little value in her eyes.
No one is telling you sleep with anyone or fall in love, just to date other women - it would make your more attractive in her eyes and increase your self-confidence & self-value.
Lately your posts just describe to me how much control over this situation you DON'T have and how much she has.
