I think there's a lot of arrogance to assume that if someone doesn't love you back, they're less spiritually evolved and that you need to keep pursuing them until they finally "wake up". Sounds like stalking. Sounds like a delusion. If someone doesn't know you and doesn't want to know you LEAVE THEM ALONE. Respect their wishes! If you love them that much!
Cause I’m going to be very clear — it is NOT spiritually evolved to stalk someone. It is not justified even if you think the universe put you together. If they don’t consent in 3D reality, no belief that “we mutually agreed for this to happen in a past life" will justify your actions.
