2 maid of honors?

I girl I went to uni with asked me to be the maid of honor in her huge wedding. I was honored, but declined because I don't have the time or money to participate (and honestly this is someone I'm not very fond of). She was upset, but we patched things up and moved on.

Wrong. Two months later she comes back saying she wants to have 2 MOHs, one who will foot the bill for a bachelorette party, bridal shower, and tea, and me as the "real" MOH who just has to show up.

Once more, I said no. But then I thought, wth? I get she wants to include me, which I appreciate, but why take advantage of someone else to do it?
