She thinks I like another girl better. How should I respond to her text?

So Ive been talking to this girl Jacqueline and we went out once. We had a great time. There is another girl I have been talking to also that I mess around with once in awhile named Leanne. Im pretty sure Jacqueline is into me. So today I wanted to see if she was gf material. I texted her that I was hungry and to please bring me food to work. I said you would so be my favorite girl. Her response was ya rite Leanne is. How should i respond to her text. Btw I brought a lunch to work. This was just a test.
