I don't think it's her from the future. When she pops back in time she goes back to her old body. She has done this a long time at this point. The toy on the train at juuust the right spot with dropping a coupon as a reminder to someone else while messaging an IRL streamer about juicy gossip. That's three right there. Sometimes she even resets everything to go through it again. Nah there's someone else.
I could see it being her from the future though. She's beyond Obsessive Girlfriend at this point. Reminds me of the Kaizo Trap Animation. She's doing all this stuff but is having nightmares about him turning away from her. What if him from the future goes to another woman even a decade later. What little sanity she currently has left would snap. She's already near that point. The only thing keeping her together without going on a rampage is constantly hugging him, kissing him once every loop and sheer determination.
