She won't care.

At all.

Female brains don't work that way.

Humans spent tens of thousands of years in hunter gatherer tribes. Where tribes would raid one another for spoils and women all the time.

Women had to evolve the psychological flexibility to survive; their families murdered, children and husbands killed in front of them, and then had to adapt to being forcibly coupled with their new husband and Bear his children.

They have the ability to utterly stop caring about things to a degree you and I cannot even imagine.

If she has left you, she has already done this. Your killing yourself won't matter one whit to her.

Brother. You are in the Anger Phase. You are passing through an inevitable stage in life as a man that we all must.

If so many others can and do get through this without needing to kill themselves, you can too.

What one man can do, another can do.

Work on letting go of your anger. Look into Buddhism, hang out with friends, make peace with having to change your worldview to no longer include this woman.

Work out, read, meditate. Build yourself, mind, body and soul.

Not only will you find peace and relief from anger, you will refine yourself into a Man truly worth knowing.
