Well, the problem with me and my girlfriend, is not that I'm not a romantic person, which I am, but that I have a real problem expressing my feelings in a way that seems romantic to her, so no I don't think he should leave, he should just open up his heart to her more (trust me, its harder than it sounds). Just tell her how you really feel about her, instead of just going through the motions. When you kiss her, tell her how much it means to you, or how beautiful she looks underneath a full moon, the thoughts are there, you just need to recognize when you have them and learn to vocalize your emotions.
