jesus fuckin christ man.. you're thinking way too much, nobody asks you to marry her or anything, come on... just go out and have fun... damn i never use the word 'date' when i ask a girl out... it's creepy... just come out meet for 20 minutes for a drink if she's not what you want, and you think there's something fishy about her, then cut off all communications, it's that simple.. the key here is to meet with as many people as you can so you have more options.. gosh you're overthinking man
You should be lucky that your friend introduce you a girl.. You should give respect to your friend. And dont screw up and dont even tell this to your friends. Otherwise she will never introduce you any girls.
