Hi azr and welcome to the forum
Your husband can take out an IVA without you, but you will still be held liable for any joint debts, and as your creditors may not be repaid anything under your husband's IVA until the end of the first year (this is quite normal!) then the joint creditors will hound you directly.
I would suggest that you try to find a job outside of the financial services industry if you feel that you will not be successful with an IVA on your record. Are you in a position to propose IVA's based on your husband's salary alone?
