The datum here comes from a STOP-Homophobia.com posting on Facebook with an affecting plea from a young Australian man about same-sex marriage:
The set-up: I don’t have a boyfriend right now, with the indefinite NP a boyfriend, in the scope of negation, so we would ordinarily expect the NP not to establish a discourse referent that later anaphoric expressions could link to. But Hutson goes on with anaphoric he: but one day I would like to ask him to marry me. Definitely a WTF anaphoric reference.
