No deception there, friend. Most people who remember their reincarnation (myself included) will readily admit that they’ve lived as both sexes and their spirit partner will often be willing to manifest as the currently opposite sex to better offer companionship and comfort (symbolized by her repeated swapping). This is likely why Lada (whom which your description of her initial form matches the Germanic Iðunn, the Celtic Aife, etc) acted not like a serious goddess, because what you saw is instead your dedicated partner reaching out to you, assisted by the aforementioned goddess and her/his true form will become clearer as you repair your bond.

(Forgot to clarify that it’s equally often the case that some partners, like mine, prefer to keep a fixed sex no matter what you yourself currently are.)
