if the hangout is at his apartment then he's 100% just gonna try to fuck again. if u want an fwb then go for it, but if ur looking for something serious then id seriously cancel this and tell him ur looking for something for serious and dont see this going anywhere. going to someones apartment THAT soon into dating is just proof he's not looking for anything other than sex
i'd stray the convo completely away from hanging at his place. u could be like "ya! let's go bowling/puttputt/ to see a movie then get a drink" or whatever date u wanna do w him and ignore the hangout vibe. then if he says something weird asf like him just wanting to chill at his place u can let him knw u don't feel comfortable going to his place so soon into getting to knw him
