I don't know why Seymour killed himself in the hotel room where Muriel was sleeping but, he did love her. In "Raise High the Roof Beam, Carpenters" Buddy reads Seymour's diary. Seymour says that he worships "her simplicity, her terrible honesty. How I rely on it." But he also says that "on the whole I don't make her really happy." It doesn't really make sense if Seymour loved her and would kill himself where Muriel would see him. On the other hand, Muriel seemed quite more phony and ditzy in "A Perfect Day for Bananafish." But maybe Muriel's simplicity really got to him in the end, and either he got fed up with her or he didn't believe he was good enough for her. Like when Muriel wants Seymour to love this kitten that she loves, but he can't automatically love it, and she expects him to love what she loves. Seymour says: "My one terrible consolation is that my beloved has an undying, basically undeviating love for the institution of marriage itself. She has a primal urge to play house permanently." I'm just basically rambling. Maybe Seymour didn't really want to get married to her, that's why they eloped. - Tyjen
