Rather unique situation, at least I think 🤷‍♂️

I'm in the military and discovered my wife was cheating on me when I returned, and had been for some time.

My wife is an attorney and makes around ~$300,000 per year. I make just under $200,000.

I am bitter.

She drafted a post nup, but my attorney says it may not hold up in court. My wife doesn't practice family law so it's certainly feasible it's not an ironclad post nup. Has anyone's spouse ever had success challenging a post or prenuptial agreement?

Lastly, and most importantly if I'm challenging the validity of the agreement and if I win that means any assets and liabilities accrued during marriage are shared.

So, opposed to paying my lawyer with a CC and paying off the balance, wouldn't it make more sense to carry the balance with a zero percent apr card?
