Who is more prone to jealousy? Orihime or Ulquiorra?

[serene__]

Maybe Ulquiorra likes independent people and want Orihime to stand up more for herself. x3

Possibly, so, but he just wants her to get stronger than she already is and to prove herself, not stand on the sidelines and do all the healing.

I don't think it's in terms of fighting to be honest.
He does! want her to get stronger, like when she defied him in her cell with the slap ( whee ) but I personally believe it's in terms of enforcing her mental strength.
He doesn't want her to be insecure of herself or rely too much on others like she does now. I don't think he tried to cut her bond with her Nakahama but simply wanted her to become an individual, not 'just a part of the group' and grow from her role as the damsel in distress

Well put, my friend
