I feel loved and cherished by my partner.

Cherished is a strange word, because we mostly use it for objects. The thing carried through three house moves. The chipped mug that survives every cupboard clear-out because somebody won't allow it in the bin.

Applied to a person it means roughly the same: kept deliberately, well past the point of usefulness, chips included.

If the feeling isn't available today, look for the evidence instead. What has somebody carried on doing for you long after the novelty of doing it wore off? That is the thing itself, whether or not it registers as warmth.
