Feeling stuck

I feel like I am going no where. I have a BA in political science and sociology but my dream has always been to go in the Army. After three kids two which are young adults and the youngest is 15; I feel that I have taken care of my family and now it is time for my dreams and the only draw back to that is that my husband says that he supports me but I can see that he is only say that to pacify me. I work two jobs compared to his one, pay the bills, and cook daily. Yet I want to go back to school and I have a way through the Army so is it wrong for me to want to go in the Army.
