If neither of you wants her to join the military, it seems you have answered your own question.
It is difficult, but there are many paths to financial security and health insurance.
Please have an honest discussion with each other about this. Cry through most of it as needed, but have the conversation as soon as possible.
Even if the job was being an accountant, but neither of you wanted it, you should talk about it and reach a joint decision.
Joint does not mean you agree. Maybe you agree to disagree.
As someone married for over 15yrs, I implore you to do have open and honest dialog with each other before making any decision that will affect you both (exceptions: small gifts, happy surprises, etc)
As a veteran, I emplore you to find income and healthcare in civilian occupations. Other military personnel or veterans may feel otherwise. Only the two of you can decide what is best for your family.
My hugs and best wishes for you with your condition and with your decisions.
Please keep in touch with us here.
