Financial Infidelity or Just Savings?

AITAH? Husband accused me of "financial infidelity" Husband 33M and

33f have been married for 10 years, together since college. Since starting out we have made financial

security a priority and have been able to achieve that, albeit with some good luck along

the way. We both have good jobs paying close to 200K each. Student loans were

paid off within a few years, both went to state schools with some scholarships so

didn't have a lot of debt to begin with, we live in a house I inherited from

my grandmother with no mortgage, and don't have any credit card debt. We max out our 401ks

and currently have 18 months of expenses in our emergency fund and are still adding to it.
