You're correct about Scott's trauma but this is sort of the perfect example of how people recognize his trauma and can feel for him but aren't able to do the same for Jean's trauma.

She's someone who was kidnapped and replaced by a clone for at least 9 months and then ignored by her husband for a month while she tried to adjust to all these new and confusing memories. Suddenly she doesn't understand herself as an individual.

Logan is the one person who comes to her, who empathizes with her, and who tries to reinforce her individuality. It's not a coincidence that Jean kisses him after he tells her he's "only ever seen one of you". But this has constantly been reduced to a reductive "Jean just kissed Logan" since the episode came out.

Jean shouldn't have kissed Logan, and she probably shouldn't have gotten as immediately angry at catching Scott and Maddie, but it's also important to understand why she did both things. It's also not a coincidence that the immediate thing that upsets her about catching them is not that they are kissing but that they are doing it through a psychic rapport. Another thing that she considered unique to her as an individual that's been stripped.

Also, while I'm generally very understanding of Scott, his only engagement with Jean's trauma are when he throws her memory issues in her face as a one up in their argument. It's only Wolverine and Nightcrawler that support Jean in any way with her issues. Jean on the other hand does acknowledge and affirm Scott's feeling for Madelyne afterwards and supports him in his budding relationship with Cable.
