This seems to me to be more about addiction (probably heroin, since there's a lot of references to injections, blood, cotton swabs, etc). I say addiction and not AIDS because he's also talking about stolen checks, lies, and empty eyes, all phenomenon that accompany an addict. But there are also good memories together, since addicts are often two people: the person you love(d), and the empty-eyed addict who lies and steals your things to get another fix.
