Megan tells her boyfriend (Hairy) her reservations about their relationship: she's happy with him, she thinks he doesn't compare to anyone else, and they have a strong connection built up over the course of years, but she's worried that all this is just because they've been dating so long that she hasn't had the opportunity to experience potentially better relationships. However, she recognizes that what she has should be enough, and resolves to stop worrying. Hairy responds to this by saying that he doesn't even like her, recognizing that it's relatively poor timing to say so after her expression of love (albeit a rather ambivalent one).
The title text is a sad-face emoticon, representing either Megan's sadness about his dislike of her, his (possibly disingenuous) sympathy for her, or the narrator's recognition that he's depicted a sad situation.
