Wow that is fast. Has anyone in her family talked to her? I would suggest talking to her physician to see if this could be a side effect of her surgery.
Has she given any concrete reason for not wanting the M? Or is it she's just not "feeling" it. If she's been suffering from depression it's going to give her the impression of not wanting to try anything. She'll focus it on the M, but it's much larger than that.
The fact that she's trying to rush things so quickly suggest that somethings up. Take back the control away from her in terms of the finances, etc. You can tell her to stop contacting your mom and others about your affairs.
