Hi Alone,
You asked what is the best way to approach him about your concerns and I say directly. At an appropriate time (not in bed, not when anyone is rushed, etc. and soon) just sit down and discuss your concerns.
Begin by reassuring him that you are fully behind him, emotionally and to some extent financially, and support him in his endeavours BUT that you do have some concerns.
For one thing you should say that in order for you to be fully supportive you want to know much more about the business, his plans, etc.
(sorry I missed your other thread, please tell me this is not an MLM!!!)
Discuss any potential problems that you may see, try to see how much actual thought he has put into developing concrete goals and objectives and the timeline for reaching those. this will be good for both of you as you will get an idea from this how prepared he actually is and some indication of how long you might have to wait for the situation to improve.
Mostly focus on your concerns and see if he has any answers as to how he might address those concerns.
At this time, I wouldn't place any pressure upon him. The above might need to be repeated at least once if you don't see progress.
At some point if his endeavours are not working out, you will need to try to get him to agree to something probably along the lines of if he doesn't reach such and such goal than he will return to work or find a job and continue to work on this business part-time.
Then at some point you simply will need to give him an ultimatum if it isn't working out. At some point it is unreasonable for you to be sole breadwinner at your current income. If you were a highly paid professional, then I would not see anything wrong with you being the sole breadwinner while he worked on his own business.
New businesses take a lot of time, I know, I have been working at my solo-law practice for more than a year now and things are still slow. It may be another year or so before I am making what I used to make at my last job and it may be four or five years before I am pulling in six figures or more a year.
to some extent it all depends on your patience and the potential for success in his business and of course how much you love him and want to be with him and what you are willing to do and how you are willing to live until things improve to the level that you desire. Only you can know these things.
best wishes and luck,
