I hate to break it to you, but he won't change after marriage. What you are seeing is a glimpse of what he will be like after. Trust me, BTDT. My husband tried "small business" ventures for years and it negatively affected our marriage. He recently stopped one and went on to another. I wish he'd stop it because I think he's avoiding his generalized anxiety with people, but anyway.

You need to express to him that he needs to decide whether or not he's ready for marriage. Clearly, this business has brought out other issues to light that may not have revealed themselves for years later. They were still going to manifest somehow and the stress you are facing is evident of it. Time to talk to him about how he's going to plan on balancing a home-based business and having a real family life. I can't believe he's said he's not ready for marriage for a few years?? Is this true? You need to get answers from your fiance and decide what to do.
