I'd say even though he did it without discussing it with you just still be supportive and if (hopefully it never does) it fails you can say you had no part of it

How you told me, tell him. Try not to feel negatively about yourself

@rainbow-baby I just didn't want him to do it with a friend and he knew/knows that. I don't think he knows how serious I feel about it though, but he's so excited about this business. I feel like I'm not being a good wife by supporting his dreams but these feelings I have are overwhelming 😖

I would be mad. He didnt take you into consideration with a big decision. Do you discuss financial things, big purchases? Id sit him down and let him know its not ok to go behind your back with anything. Its more of a trust issue.
