What should I do about this guy?

Just last Saturday, I went out with a guy I met on the website Tagged. (After he met with my parents.) We both went to go see Terminator Salvation and had an awesome time. However, after we went our separate ways for the day, he conversations with me have been very brief because of family problems. Should I take my younger sisters' advice and go out on a second date with him? And if it works out, should I pursue a romantic relationship with him?
