Awful dreams about my Husband leaving me !?

Although you say that you have no plans to change your single status, these dreams indicate a fear of abandonment and loneliness. Subconsciously, like all of us, you yearn for the warmth and sharing of another's company and as you head into old age ( sorry but there myself ) so the prospect of a solitary and maybe miserable old age looms ever larger in your mind. Whether you can come to terms with the prospect of a solitary existence or whether you will change your mind and look for someone I can't say, I don't know you well enough, but certainly you have more issues about it than you admit to, even to yourself.
