My fiance tried to kill me?

There should not be a limbo. You dearly love the man you thought you knew. Things have changed in a major way. Stay as far away from him as possible. Don't have any contact with him ever again. Hopefully he will spend a long time in prison. It would be a good idea to get some professional help. This is a very traumatic event and it's important that you have someone that can help you work through what happened.
