I dunno.. I told my ex i was leaving flipanim. Then i told her i got a new acc (this one).. She followed me then.. Just completly started pretending that i never exsisted
Maybe because she was used to you being on your old account she could've forgotten you made a new one?
The best thing you can do is ask her about this and tell her you feel ignored. But I'm really sorry this happened to you. I'm sure it's Just a miss understanding.
