<human>: I've[M] made many mistakes over the course of the six year relationship, with many ups and downs. My girlfriend has put up with a lot of my shit over the years. I have issues with depression, anger,and possible PTSD from two tours I'm Iraq. When we first met things were great, as the years progressed my issues got worse and I never addressed them. I started to abuse alcohol and drugs to cope with my life which made our life worse. It came to a head two Sundays ago and she left that night and never came back. Now we're both seeking treatment for our issues. She tells me that she still loves me but the amount of pain I have inflicted on her is something she can never forget as says we'll never be together again. Is there a possibility that if we both get better that something can happen over time? Is it possible to get that love back or is it to late?
