(((e))) I know this is a terrible time for you. I was in the same place last August, when my h moved out. I was just devastated, but now I can see that it has been good for him to move out. It was also good for me to have some time away from him when he was in that "alien" stage. Now things are slowly improving, although I'm a little scared to even type that here.
Try to use this time to focus on yourself. Make two lists of goals- one for yourself and one for your R. Post them here and we will try to keep you honest or maybe just keep nagging you about them Hang in there, you WILL get through this!
