Is it legal for my HUsband to cancel my credit card?

If the credit card is in your husband's name, then he can cancel the card if he wishes to do so. It would be best for you to have a conversation with him regarding money and each of your goals. It may be that he felt that you were spending too much money or there may be another reason. A marriage is a partnership in which both parties need to be happy with the arrangement. If you cannot discuss these matters with your spouse, you may need counseling. You can also assess your situation and determine if working is a better option for you as this would allow you to have money and more independence.
