Quiet boy

I’ve been seeing this guy for just over a month and he took me out on a date yesterday. It was really good, but on the way back home he got quiet and so did i. He usually gets quiet towards the end of dates and my friends say he probably just gets nervous and doesn’t know what to do at this point. He kissed me goodbye and everything was good. Why do u think he goes quiet and should I worry?

Another thing: we only text to make plans. I don’t think he’s big on texting anyone but his friends. He’s always been like that tho
