The parallels between their first and most recent fall out are mad, I remember Lindsay saying she felt she couldn’t discuss her new relationship with jimmy because Jenny was just seething, and Jenny would cancel any plans that involved jimmy (which eventually became them all when he moved over), but I’m pretty sure Jenny said she felt she couldn’t discuss her relationship with Evan to Lindsay because she was so mad about it too ( because she was really struggling to find someone). It’s mad the parallels, it really seems their friendship was too all consuming to have any third parties involved
