You are feeding off each other's negativity, which is making both of you unable to move forward and see the "bigger picture".
Your "dream" is not being realised at present because you are mired in self-pity that you can't be what you want to be ie touring musicians.
But you will never be what you want to be by constantly feeling sorry for yourselves.
At present, you haven't "made it" (your words) in the music business.
This will never happen if you continue the way you are - you need to work to live, yes that's true, but you must have free time when you are not working. Use this time in a positive way to improve your musical skills, make contacts, network, put yourself out there.
Eventually the day may come when you can "give up the day job" and concentrate solely on your bit passion, music.
But this will never happen if you and your husband continue to cry all the time because your dream has not fallen into your lap.
Get out there and make it happen. It's the only way.
