SR, if you are still working with Larry my advice is to not contaminate that with strategies here...
If I had to guess his hoarding money is
1. Passive aggressive - he's feeling guilt from the affair and wants to act out 2. He may be buying OW expensive guifts 3. He may be experiencing reverse mistrust.. He may think YOU are hoarding money so he's cutting back to offset what he thinks YOU may be planning
THose are guesses... could be other reasons... but those are all possible...
