I was shipping Ten/Rose as bros for a while but Rose's attitude towards anyone else who wanted to come along was annoying. I didn't get upset when she left, but Donna reaaaalllly put me off. I'm glad there's Martha in the meantime because I'd have been kicking up a storm wanting Rose back if I had to go from delightfully useful Rose to sarcasm and useless Donna off the bat. The Doctor didn't need her sass at that point in time.
