<human>: Hey guys and ladies I have a question to ask. I have been dating a guy  I met through my housemate for around a month.  He's been wonderful and sweet during our dates. This past week he invited me to meet his parents and to spend the weekend together in a different town. Everything had been going well until our last day together. In the morning he didn't talk to me, the car ride was nearly silent. When he said goodbye he just gave me a hug and no kiss. I thought at first that he was tied but he's usually not this way. I know I need to talk to him, I have been texting him with no reply. What should my next step be?

Give me the gist of the text in a nutshell
<bot>: been dating a guy for a month+ go on a little vacation on the way back he acts very distant. Hasn't replied to my attempts to contact him.
