I think you are being unrealistic if you think that you will be able to hide an issue as large as this. Just the issue of a bankruptcy is on public record. Candidly I am sorry to say that your choices are bad and worse.. When you give him the news you will be upsetting him. If he finds out on the sly he will be even more upset. You may feel more secure in a counseling setting. But it is my firm believe that you will;l have to tell him and it is better if you tell him rather than he finds out. This is opinion not fact. but I have seen it play out several times. Best wishes.
