XOXO

no help?

I would let her know now that although you're not assuming she would ask you, you want her to know that you could not possibly take on the responsibility of being her MOH while planning and finalizing your own wedding - - - that you just won't have the time OR MONEY to commit (the time and attention she deserves, you might say . . . . ) AND give your own wedding the time it needs and deserves!! I would more than encourage her to choose someone else, I would just let her know you cannot do it. If she gets angry and tells you not to be in it at all, that solves two problems, it would seem.

That's what I would do, but you know her, so 'handle with care.'
