Nope, I think its all good there...

Do you think you have wasted anymore $$ than your H has?

Next time he brings that up just tell him you've done the bookeeping and you both have wasted money...

If you want to do the work and add it all up that would even be beter... I strongly suspect you will find he's wasted no less than you have...

He is accusing you of financial infidelity, but he really doens't have any case here... It's just him being accusatory... And yes I still suspect its a smoke screen
