Hi

If a man proposes to his ex-wife again, how would she say the following to him in a natural manner? Is the following correct and natural?

Hi Tom,

Bit of a mouthful!

Marry you again? What would I say to all those people who I have been speaking ill of you to all these years?

I would shift the 'to' as follows:
