I am a companion to my grandfather in an assisted living facility. He has dementia but is otherwise pretty healthy for 93. He has a girlfriend at the facility - they've been together for four years (just hugs and kisses). I recently found out from a PCA that she is having intercourse with another resident when my grandfather is not around. What am I supposed to do? Please help with any suggestions...I hate for my grandfather to be put in such a shameful situation.
