Oh good gods no!!!!!
The Neelix/Kes thing was just down right creepy from the beginning. I always found it verging on him grooming her for a while. They could have made it him rescuing her from the Kazon, so she saw him as her saviour thus creating a strong friendship between them (which would see her give him a lung a few episodes down the line). That would have done the job just as well.
I was so happy when they split up. It seemed to do her the world of good as well, she grew her hair out and replaced all the cutesy clothing with more practical outfits
