First of all, I'm sorry you find yourself in this position.
Second....please protect yourself financially. Run a credit report to make sure that he hasn't been running up debts that you don't know about. Go over the books for the business. Make sure he isn't hiding money. See an attorney to learn your financial rights.
He might just be temporarily besotted in an affair. Or he might have always pined after the old girlfriend and now that she's making herself available he believes she's the one he should be with. He may be failing in the business and trying to hide that from you. Or he may simply be an irresponsible Peter Pan who doesn't want to grow up.
It's even possible, given your admission that you have been the breadwinner, that he used you to achieve his dream, and now that he has it, doesn't need you.
I'm sorry if some of these possibilities sound harsh. You deserve someone who adores you and wants to be an equal partner. Sometimes when we love, we ignore big red flags waving in our face.
Were there red flags about him that you ignored? Why do you think you picked such an immature guy?
