I think this is especially true for couples – money spend doing things with her will satisfy her more than 购买ing her stuff. Based on that, I suggest a majority of 的money you spend “on her”应该去吃晚饭，看电影，跳舞，博物馆，一日游，度假等等。
如果资金紧张，请寻找方法“buy” experiences on 的cheap. Make a picnic meal and take a drive to 的beach, 的mountains, a national park, or some such. Find a way to go to movies when 的prices are lower. Look for deals on off days and at non-peak times.
If you are not struggling financially there are great deals from vacation locations hurting for income. Maybe it is time for 的vacation you have always dreamed about.
