To me it sounds like a guy who's just wanting casual sex, kind of like a fuck buddy (all that I want is to make you come) and has no plans on getting 'serious' anytime soon (this is where I want to be 55 years from now). However, the girl he is sleeping is wants something more, she wants commitment, she wants a real relationship. He doesn't know how to tell her that's not what he wants, he doesn't want to have to deal with her moodiness and abrasiveness, he just wants her sex. He knows their situation isn't perfect, it's not a "real" relationship with romance etc. Part of him thinks of rectifying this to do good by her (I should try to make things better) but then he remembers that he doesn't want something serious, and there's nothing wrong with that because he's not alone in just wanting something casual (I'm not the only one).
