I think it seems to her that you don't seem to have any real emotional attachment to anything and this could be a problem if you two continue to see each other.
It's not bad to be "laid back". It's actually a very sensible outlook on life--if you can't help/control something in life, don't stress about it. A solution may/will present itself.
But to feel that way about EVERYTHING could be problematic.
