Died 3 times trying to escape the normal way, think 'fuck it, might as well woo her'.
Told her that we should go see the world together, she said this place was paradise, and we should never leave. So I said "Everywhere in the world is Paradise if I'm with you." She immediately changed her mind and opened the door.
But I wasn't done yet. I asked her to leave with me, but she said she couldn't leave. I told her to come with me, and she asked me to promise her to stay together with her. I said, she can stay together with me, and we both walked out the door.
Overall, I think taming Yanderes with love instead of trying to escape has a good success rate.
