Getting married

Hello all so I’m currently engaged to the love of my life and my absolute best friend. He is currently at itb. I miss him so much and look forward to being able to call him at night when he is off. He starts training soon so I know there will be some weeks of “radio silence”. Long story short he hopes to get leave in November and wants to get married then. I would absolutely love to get married when he comes home but my family absolutely hates him. I don’t know what to do because as soon as I marry him I will be kicked out and I’m only 18. I am attending college so I can’t work a full time job and go to school. I know my fiancé would support me but I don’t want him spending money on a place for me to live while I finish school. I just need some advice right now
