I created a tinder account about a month ago, and to my great suprise my profile is actually doing quite decent(about 150 matches in one month). After some messaging back and fourth with some girls, i've managed to schedule a date with two different girls this week. The first girl I don't really see a girlfriend potential in, she is really nice and all that, but I think we are too different to be other than ff's. The second girl on the other hand I really want to see if we possibly could build a relationship. So fast forward to my question... In what way should my approaches differ towards the two girls consider what I want?

English is not my first language btw, so tell me if something is unclear.
