In laws and marriage. I need advice!

Hello!

Ive been talking with several people like my dad my mom... etc.. and still I find my self "lost".

I met someone who is afghan and I am lebanese. So were pretty different...

So in my culture Its very much like the west. A couple gets married they Both move out and live alone but! In his culture they dont and I have to live with his in laws meaning his mom his sister and his brother. Since I am lebanese I am arab and yes I am a muslim therefore I wear the Hijab. Wearing the hijab means I cannot take it of in front of anyone who is capable of marrying me. So if was not married to this I guy there is nothing wrong with being married to his brother and therefore I cant take it off. Which means not only I cant wear "whatever I want" lingerie and all that I cant even take of my scarf! Which is horrible... I never imagine my marriage as living with my in laws I mean no privacy no nothing I wont get the pleasure of furnishing my own home. I told him several times I cant imagine my self living with my inlaws he is not willing to "comprimise" hes not willing to move out. He said in the future we will but I cannot guarantee anything nor can I tell u after how long well move out. I dont want to be in a marriage where I am waiting for his mother to die or his siblings to move out that's just wrong. Hes a good guy he has good traits and qualities that I look for in a guy but sometimes I feel like he is asking for too much. It's hard to even marry someone not lebanese due to cultural thoughts and backgrounds but hes also asking me to live with my inlaws and yet 1 comprimise hes not willing to Make. His mother doesn't speak English and I have to learn dari. He keeps saying my mom doesn't care what you do but I doubt that. I need some advice.
