My ESFP wife digs the "Five Love Languages" thing, see
The 5 Love Languages | The 5 Love Languages®
I looked at the book, and it did not speak to me. What would make my imagined ideal relationship special to me has something to do with unexpressed or half-expressed clever cues. I say imagined since I never found that. But an example from a past INTP love interest: we both liked 1776, so I once signed an email, "Saltpetre, <my name>." She responded normally, and signed hers "Pins, <her name>"
That made me feel warm & fuzzy.
The five seem too concrete, circumscribed. Mental synergy perhaps?
