What was your most painful break up like/over/how old were you, etc??

Wow, my first marriage. We lost contact for over 20 years, until recently when she found my email address and wrote me to see how I was doing in my life. We exchanged phone numbers, big mistake, from that point on she insulted me. I held my tongue through it all. I finally took her out of my phone contacts and moved on. I'm truly better off without her drama. Long story short, I am done
