I think that she said it in a good way and such a statement is always positive. This is because, when talking to an old friend, you always discuss your past life and you tend to compare it with your current life hence you note that there is a change, whether positive or negative.
this is a difficult question to answer because (and maybe its just me!!) i would need to know more about the conversation. in what way has your life changed? what was the persons mood and frame of mind when making this statement-so i can only say that you already probably have a pretty good idea whether that statement is good or bad!
