I think the story is they were in a relationship but he really traumatized her. As for her posts, they always just come off very not genuine. She's always moving around, always in some strange place, and always having some weird issues. It feels like she posts things she took 6 months back before going on another crazy ride. I don't think she's on anything, but it's like if you've ever personally known someone who goes on month long drug binges.
