Assuming that you and your husband still live together, you will need to involve him if you intend to propose an IVA, as details of his income will need to be disclosed. This does not necessarily mean that you have to tell him about the IVA, but most professionals would advise that this is the most appropriate thing to do - although I do have clients who have refused to tell their partners.
I have also have had many clients who have been worried to share their difficulties with their partners, but then at the end of the day have changed their minds, and have felt a lot better for it. Pluck up the courage, as I am sure that you will feel a lot better.
