Hithere
OP
You are severely under reacting
You are stuck looking at a leaf (the check) and ignoring the forest (the overall situation)
How financially savvy are you? From your comments, sounds like not much.
You are 10 years younger than your husband.
Are you aware of passwords, what accounts are setup where, due dates of bills, how much to pay every month know bills, how much money on both accounts, etc?
If he is not able to be earn or passes away, you are left with a house and your account. A house is not a liquid asset like money in the bank.
How are you planning to support yourself? What money to use? What budget?
Are you assuming other people will step up and help you if he dies (family members, for example)?
Instead you are scared you are "hiding" a check that came under your name, scared of his reaction.
That says everything.
Please get your head out of the sand and dont be an ostrich.
You are in trouble as your financial future is not planned.
Actually I'd be making enquiries about his will! It's not always the case that wife gets the lot automatically! Not if he wills otherwise, in which case you'll be age to fight your corner and prove your worthy. He sounds an absolute horses rear end(sorry Dobbin) worse things have happened but not often!
