Well since I'm siding with Maka , I have to say her being jealous just because she can't understand , why a fool (ehm no flame) like Black*Star can be stronger just with physical practice , yet she struggled so hard to fight to be stronger but can't beat him yet. (aside from her smart way to find enemy's weakness when she attack + witch hunter + black blood)
I do love her for being jealous , reminded me that she is still a child , and have a bad side too. Can't say much either. She is a girl , so maybe that's why she's so emotional
