threesome request where she clearly didnt want to be there...

so im a single F (lifestyle term, im a woman looking to play) and a couple invited me round for a "relaxed mff threesome". got to theirs in dublin, she opened the door looking like she was about to cry. he was loud, in control, pouring drinks before id even sat down. she went to "freshen up" and didnt come back for 20 mins. when she did her eyes were red. i made up an emergency and left. i still feel guilty for not... i dont know, doing something more for her? what would you have done. im 18+ obviously and so were they but jesus...
