Love Life (Please Help)

Okay so me and this guy talked gor a long time and he finally asked me to be his girlfriend he is very attractive and we went on our first "date" last Friday we went to go watch a movie and i had a great time he was so sweet and respectful but we have not hung out since last Friday i mean he always says he misses me but why has he not asked me to hang out again?? today he texted me saying he was heading out of town to watch the purge w his "best friend" but i have a weird feeling about it i mean his 'best friend' could be a girl or am i just overthinking?
