Why would a Husband hides money in his car?

Answer 1

Probably he's saving some for a surprised birthday gift. Or in other cases, he's running low on cash for his personal needs, to buy other stuffs. It's very unlikely that that money is used on another woman.

A husband might hide money in his car for various reasons, including concerns about privacy, financial independence, or unforeseen emergencies. Some individuals may prefer to keep a financial reserve separate from joint accounts for personal reasons. However, transparency in financial matters is crucial in a relationship, and open communication about money is recommended to avoid misunderstandings and foster trust between spouses.
