I would try to address those things that ALIGN, between her list of marital complaints/things she'd like to see more of, and the Love Languages.
In other words, if she seems to score high in Acts of Service, Words of Affirmation, and Quality Time (and not so much in Physical Touch and Gift Giving) . . . but one of her recent marital complaints is that you don't spend enough time with her, then I'd start with that.
