Marriage. Boyfriend. Military.

Taylor • ttc 👶🏻 engaged 💕💍
My boyfriend and I have been together for 4 years. We're ttc. But aside from that, he's working on getting into the military. We both want to get married. Have a nice wedding. Nice honey moon. Nice rings. But we don't have money for that right now. He wants us to just get legally married thru the court or whatever so we get more income from the military to pay off our debt and then when we have the money to have the ceremony and stuff. And he doesn't want people to know until we have the wedding and what not because he feels ashamed I guess that we couldn't afford it right now. Thoughts? Advice?
