For The Last Time

Goodbyes are a bittersweet part of life. Everyone says them, sometimes they're for better, sometimes for worse. Real goodbyes are forever.
Tonight I said goodbye to someone who had a huge impact on my life. She was an amazing friend until she betrayed me just a few months ago. I told her it'd take time but I'd try to forgive her, but I guess I never really could. When I got really depressed, I thought she understood me the best so I talked to her instead of my best friends. I made a terrible, dangerous mistake by doing that. Now, I can't blame her for my actions but she put the idea in my head.
After months of healing, tonight I knew it was time to say goodbye to her, for the last time.
I thanked her for the terrible memories.
At first I had an adrenaline rush as I realized that I could finally end a miserable chapter of my life, but now I feel sick. I feel guilty for not making it work but I wonder if it ever could after what happened.
I know I can't go back, and I wouldn't if I could. What's done is what had to be done.
We've said goodbye and now we'll both be on our way.
