The thing is, this friendship started four and a half years ago during an extremely traumatic and stressful time in my life and hers both, which left us with a friendship, but also left us with a "trauma bond." Although neither of our situations at the time were related, we'd bonded over the similarities. Sometimes, friendships formed in this way will last a lifetime. However, in many cases, they will simply end over time, once the time of crisis is over with.
When you bond over something in your life that is awful, once one party - or even both - begin to heal and move past the trauma and stress of the situation, it becomes difficult to maintain that relationship if the sole glue holding the relationship together is the stress and turmoil of the situation you are in. In effect, these friendships will typically just "fizzle out" over time. In this instance, the friendship "imploded."
While I am proud of the fact that I did not resort to name-calling or personal insults, I did not raise my voice or say anything intentionally hurtful, I am hurt by the fact that she resorted to such tactics as she got extremely volatile when I set boundaries in place to protect myself and my mental and emotional health from a situation that she had going on.
I feel many things about this friendship ending - loss, sadness, frustration, perhaps a bit of anger, regret... and mainly, relief. I saw this coming a long time ago, although I don't think she did. I saw it coming, couldn't prevent it, but still kept trying to maintain a friendship that had itself become toxic for me. As our friendship imploded, I felt the tears roll down my face.
I love her and I will miss her. But I welcome peace and healing.
