Is it fucked up? People experience strong and conflicting emotions when they meet someone who reminds them of a former relationship or someone who has died. I think Steven's outburst was used to lampshade the weird and humorously dark side of the situation.
However the show is generally more positive about people, relationships, and personal development than that. It would not fit that Pearl stays broken and unrequited forever. This episode seems like the beginning of Pearl evolving, and exploring what makes herself tick. Unnamed Pink Human's appearance was just Pearl realizing she has a "type". Pearl has suffered from seeing Rose as her validation for existing. Pearl only felt she mattered when she did things to please or honor Rose. Now Pearl starts to see there are things she wants for herself.
