Count on ups and downs (III)

[WillDo]

That's very kind of you. Thanks!

30% of the total income is the amount my W taking away. Previously, the money would go to joint account and the surplus to the saving pot for use on various stuff. My total earnings reach double of hers. She hasn't withdrawn money like that. But now just sends her income to her own account. I know that she has spend money on OP. Birthday present, eBay purchases. Not on a large amount but I suspect that she then start withdrawing small money but frequently and spending cash so that there is no trail.

I am not sure how to deal with it. As you know communication with MLC is awkward.
