Marriage??

My boyfriend and have been dating for about 6 months now and I believe we are both in love and committed. I’m only 20 and he has asked me to marry him only after 6 months. We’ve known each other since pre-k and I’ve loved him my whole life, but I feel we might be too young to get married and start a family. Our families are well off and because of that he suggested I be a housewife, but I don’t know about having kids and being home all the time it just doesn’t suit me. So should I say yes or give it time? Btw he’s also 20
