Aye, sounds like a bit of denial. Or maybe your "hints" have simply not been direct enough. When she uses the wrong name and pronouns, do you correct her? Did you say anything when she was talking about the guy on the news? She won't come around all by herself, people get very set in their habits and you'll have to beat people over the head with "it's he/him....my name is actually this....you do have a child like that mother" over and over and over again until it sinks in.
