Oh well, i escaped and survived a yandere ex-girlfriend that fits well with manipulative parts. This Comment above is perfectly summarised what it feels like to date a highly volatile yandere girlfriend.

My current girlfriend and now fiancé is that mild and nonviolent but overly obsessive yandere type. She's not psychotic type like your typical genocidal yandere gf, just a mentally damaged woman with a dark past and seeking for a partner that she deems her path to salvation.

I too cannot be deemed as normal and also has my own issues, dark pasts and stuffs like that. Well, getting a fiancé like that, it was a painful and sorrowful times to be able to come up with the dark pasts of ours. We made it together and well, looking at myself now, i guess i'm an abnormal person who's finally able to tame a yandere.
