At first glance, this song seems to be about any other painful breakup. He wants to forget, he tries not to care, but it does not work (first verse). The second verse is him reminiscing about better times, when they were still together. The Top seems to be a metaphorical place, the place where you are when you're happy and everything is good in life. And then he realizes all he really wants is to get back together.
But digging a bit deeper in The Cure's history at that point, you realize this lyric is directly addressed at Simon, who he hadn't spoken to for over a year. Actually, the last line suggests he may be directing the song at other former band members as well, like Porl. Of course, they did come back in the end, and thank heavens they did.
The above comment is correct.
