I'm not going to beat up on dude....we've all been manipulated. Sometimes it takes a decade to realize you are losing the battle - and things slowly turn ugly, it's not like this all happened in a week.
I have a good friend that was in the same situation. He lost 10 prime years and she just turned him off like a switch and got back together with the baby daddy. He raised basically a newborn to 10 years of age as the real father. She was bipolar, narcissistic personality disorder, borderline....whatever you want to call it they are all similar in modern women. These traits are rewarded, not shamed in the age of social media.
Run Taco, and consider yourself lucky it didn't take longer for the same result. Keep busy, don't dwell on what you never had anyway and work on yourself. Women are only attracted to men that provide and protect.
