i wish i could tell you that it gets better...early menopause stinks. Hormone therapy is her friend and yours. Relations become a chore for her without them and you will be made to feel guilty for even bringing it up. Approach with caution and try to be understanding is the best advice i can give you.
There is an upside when they have their personal weather moments. In winter, I let her go to bed first, she warms up the sheets.
