I'm sorry to hear about your health issues bro, but that's all the more reason to let go and move on, life is too valuable to waste dealing with a woman like that, she will destroy you.Narcissistic rage is dangerous ,and don't worry about another man raising your child,women like that can't keep men lol also look up female autism,usually not diagnosed until adulthood since females are naturally more sociable it hides the symptoms, 8 out of 11 females are on the autism spectrum and narcissism seems to be the default personality of that type. Live and Learn ,let go and move on and make the best of the life you have. I know it's not easy,I've done it twice,but I'm smarter now and know what to avoid and you will too when you study cluster B personality disorders and you're role in it. (once you learn about cluster B psychos the dems/blm/antifa/deep state will make a lot more sense to you.) My final word of advise,get a motorcycle.
