whether or not he's egotistical enough to try and "turn"
op is debatable since we don't know what what his mindset is.
since getting him to stop pursuing her hasn't worked and she wants to still be friends (not possible in this scenario, imo), then i'm going to hazard a guess that she hasn't made things blunt enough to him.
op can correct me if i'm wrong but i got the impression that because she wanted to maintain his friendship, she might have tried to let him down gently.
even though op may think it's apparent to everyone that she has "an extreme case of jungle fever"
, dude may not actually be aware how deep her love of white men runs. maybe he just isn't aware that she dates non-blacks
exclusively (i.e - no black guys). it's a fair mistake to make, imo, since i'd say the majority of society dates within their own culture/race.
op needs to set him straight that he will never ever get a chance with her because he's black and not white (or another race).
