mindfull, this doesn't sound like harmony to me. Your health is suffering, mental, emotional and physical stress.
Time for you to cast your own shadow again. Take care of yourself.
Not to think for or excuse your husband but the money issue is big to a man. The IRS problems probably make him feel like a failure to you (he can't provide for you.) Would it help to simplify your life?
Cheers
