oh, Angelina you poor dear! Don't get me started on middle aged men and "bimbos". He's your dad and you love him dearly so I totally get that, but still the bimbo will blind him.
Hopefully, you can communicate your feelings to them in a tactfull way and let it be known he is your Dad first and you would appreciate her at least asking for your input. This RSD should should not rob you of your input.
