It is so hard to imagine someone we have loved can turn into someone so awful. Now my H is even shocked at his own behavior when he looks back on the past year.
Try to breathe and ground yourself in the moment. Right now, in this moment, you are ok. You are going to be ok. Remember what you wrote ^^above^^ about how well you have handled this. You can hold your head high no matter what he does or doesn't do, says or doesn't say.
I am very sorry for your loss. Right now you are grieving and that is magnifying all of the other feelings about your H. That will settle again too. more ((hugs))
