The author is a therapist. I know, big surprise :-) Although I haven't read the whole book there's a chapter there "Loving the Unlovely" where a client is facing a partner who "doesn't get it." Gary, the therepist, suggests to Ann, the client, that she figure out her husband's, Glenn, love language and start speaking to it. It took a leap of faith but she did. After Glenn reacted positively she waited a week then asked Glenn to respond using HER language. Repeat.
In this particular case it took about 2 months for things to improve dramatically. Your milage will almost certainly vary.
