I'm so sorry you're having to go through this. A fellow nurse co-worker and very good friend of mine for many years was murdered by her boyfriend a couple of years ago.
He took a plea deal, LWOP. His siblings and mother were ready to testify against him. My friend,Clo, was an only child and a dog lover like me. We had so much fun and worked so well together in our early 30's.
I'd moved 1,000+ miles away a few years prior, and hadn't seen her in a long time but we still texted. She was planning on flying out to visit me for a week just before she was killed.. We were making lots of fun plans, as she'd never seen Texas before.

00 My last text from her was just before she was murdered. It was a photo of the cutest little dog I've ever seen. She'd just rescued him from the shelter she volunteered for on her off time. He shot and killed her dog, too. She had no family living.
Because of Clo's murder, shot point blank in the head with a shotgun, I don't want to hear 911 tapes. I don't want to hear victims screaming or a perp. shooting a gun. I can tell you that with time, if you're like me, the nightmares will stop, and you will have funny dreams of the two of you working together and doing things together outside work. It's amazing how our minds fill in the painful spaces with sweet little things as time passes and we heal from the acute loss. I hope so much this happens for you. We still remember them, but we learn to live with what happened to them... becauses we have to do so.
Hugs!!!
