This is parts of the reasons the rich will continue to marry the rich while the poor does the same. Your wife behaves like someone who hasn't worked hard for money before, so she doesn't have the mentality that someone that supported her business with his hard earned money needs to be supported too. Bro, trust me, she's said exactly what she would do and that's what will happen. Infact, it might even be worst. Have seen several of such cases to the extent of ordinary pencil, the lady will ask her daughter to wait for her dad.

See, here's my advice for you. Please, support her business but drastically reduce the support amount to like 300 to 500k and use the remaining to invest in yourself as you can see that, you now have a load of task ahead of you.

Once you support the business, guide her in upgrading to a larger space and more machines just the way you want. This, you aren't doing with your money but her money. Only advice and guide her.

Lastly, as times goes on. Bring in tactics towards her supporting the family. I wish you all the very best!
