The "best revenge" is going to be your evolution and becoming the man she can't replace with anyone better. Strive towards improving yourself every single day. Effective implementation and action assures your transformation. Onwards Gentlemen.

"Controlling" - he wouldn't let you be a 304. "Verbally Abusive" - he voiced and enforced accountability and his standards. "Emotionally Unavailable" - he wouldn't argue with her to satisfy her emotional stimulation needs. If you do decide to stimulate, make sure you're always the cause (you're consciouly triggering her) and never the effect (she's triggering you). "We Grew Aprart" - her single friends more than likely convinced her to want to be single. Birds of a feather, flock together.

"Man is made or unmade by himself; in the armoury of thought he forges the weapons by which he destroys himself; he also fashions the tools with which he builds for himself heavenly mansions of joy and strength and peace." "By the right choice and true application of thought, man ascends to the Divine Perfection; by the abuse and wrong application of thought, he descends below the level of the beast. Between these two extremes are all the grades of character, and man is their maker and master." - As A Man Thinketh

So Is He.
