OK. Here we go. I've seen quite a few dreams with the same basic themes as this one. But the unique elements of your dream can furnish me with the clues to the unique aspects of its message to you.
1. It's unique that your dream begins with A. husband comes back, B. you're very excited, and C. he is affectionate with you. A. is NOT a unique element, but B & C ARE very unusual. B. implies that either he hasn't come back much in 6 years or you haven't been excited much in 6 years, or BOTH. C. implies that HE DOES LOVE YOU still, and you love him still--which is normal. But it's very important BECAUSE of what he says next: That he's going to marry another woman. How could he possibly want to marry someone else if you still love each other? Because he's DEAD, and you're ALIVE, so he can't be married to you!
So you were4 FURIOUS. You proceed to plead that hye 's out of line to marry someone else AFTER ALL YOU DID FOR HIM IN THOSE LAST TWO YEARS. You sacrificed so much, and you deserve his endless, undying gratitude instead of romantic betrayal! But he has died! Are you still counting on the gratitude and love of a dead man to reward you in your world from which he's been gone for 6 years? You insist that he was the love of your life. But you have a lot more life to live, and he's not ever going to be around to live it with you.
I suspect (and here is where my previous questions were meant to get information for this guesstimate) that when you were caring for him so affectionately during his illness, and even after he passed away, that you never let yourself feel the full force of your ANGER and OUTRAGE that you were going to lose--and then had lost--the love of your life, and there was no way to stop it. Feeling ANGER at the lover you have lost for him abandoning you (even tho you know rationally that it wasn't his choice to leave you) is very hard for a grieving woman to achieve; but it is essential for working through the grieving process. SO THIS DREAM MAKES YOU FEEL THAT ANGER. Because he is voluntarily LEAVING YOUR FOR ANOTHER WOMAN: That is the key element of this dream that I have seen in all of the other dreams of this kind from women who have lost their beloved husbands. Most of the other women who've submitted these dreams have not explicitly said "he was the love of my life," but they've probably believed it. And most of the others have had this kind of a dream between year one and two after their loss; and yours is coming at year 6.
You are outraged that he is leaving you for another woman, when he has already left you by dying 6 years ago! You have not allowed him to die inside of yourself. You given him permission to leave you in death, and you're angry because you treated him so well when he was sick, and now he wants to leave you (what was the other woman's name?). In this dr3eam, the Dream Director (aka God) might be showing you that you can't make him act the way you want him to after he has been dead for this long, so you should let him go aweay from you. He's actually suggesting backhandedly that he can love somebody else in the realm of the afterlife; so you can love somebody else in the world of the living. This dream-movie's moral teaching is to stop living in your past and start finding a new future for yourself--even if it means loving other people, whether it's romantic love or not. In addition, if you have been in the habit of thinking he was an ideal husband, so nobody else could ever be as good, the scene of him telling you he was going to marry another woman (with a real name, which MUST mean something I can't understand without conversing with you about her) is intended to get you angry enough to push him off your pedestal. So then you'll be able to look at other people around you as good enough to love --just as he is still good enough to love (because of his affection for you) and good enough to give you implied permission to love somebody else if you should feel like it.
I bet you're young enough (40s or 50s) to still have a lot more life in you; and I hope you'll respond now that I've stuck my neck out to interpret your dream and your anger--which is the energy to blow a hole in what could be a very frozen/stuck place in your personality so that you can begin to thaw out and begin flowing forward in your emotional life again.
