6 years and done.

I feel so heartbroken. My husband of over three years just left me and told me he wasn't happy and hadn't been for a while. I just feel so empty. We've been together since we were both 17 and I honestly don't know how to do this. I don't know how to start over. I know people do it all the time but I just hope somehow I'll get the strength to keep moving forward and not look back.
