Polly keeps saying she doesn't know where she stands. She does. She just doesn't want to accept it!

Sorry, but Adam has been clear from day one. The experts and damn near everyone else has gaslit, guilted and pretty coerced him to make it work with her. He likes her as a person but is not attracted to her. He doesn't want to hurt her, but he doesn't fancy her.

That's why the PDA and reassurance isn't happening. Look at the difference between his interactions with Lacey and Amy. He was smiling, flirty, tactile. That's because he was attracted to them!

Deep down Polly knows this, but she's so desperate and has such low self esteem, she keeps trying to force what she knows isn't there.

Adam is not the bad guy here. No matter how she tries to spin it. The blame is squarely on the experts and everyone else who basically coerced Adam to give it a go with someone he wasn't interested in.
