OK, this first thing is, It is you that I am worried about. This is not going to happen over night. He is lashing out here. This has nothing to do with him loving you. Which I am sure he still does. He is going through the grieving mode, and I have been through this. He feels that you will not love him anymore due to his near fatal accident. Now you have to give him some space. And you my dear need to seek some counseling for this. Remember, this is the person you are going to marry. This happens and it is normal. He has alot of healing to do. A lot (and I mean a lot) of therapy ahead of him. You still have to be buy his side. I is not going to be easy. You giving up on him way to fast here. Ya know grieving does not have to be about death. It is about loosing ones ability to be the person you once were and the life you use to lead. Once he goes through rehab and starts getting his life back totgether you will start to see small sutle changes in him. I still say he will come around. Now, after he regains most of his life back. If he still feels this way, then and only then would I give it up.
Now, on the other side of the coin. You are going to have a lot to deal with here. You are going to need the streangh to either stick with him or walk away. That has to be your choice. Nevertheless, this is going to be just as hard on you as it is him.
If you need someone to talk to, please PM me and seek a counselor. If you love him enough, you will see him though this.
Now, it is time to give him some space. Stay away for awhile. I know it is going to be hard but you have to do it. This will give him time to regroup and think more clearly.
I am worried about you. Very worried. Please keep in touch.
BTW: My name is "Carrie"
