Definitely sounds like a conversation about it is needed then, it’ll do a lot less damage to get that straightened out before he assumes y’all are gf/bf and not just dating. I told a guy I was just looking for something casual and after the date he said “so you’re my girlfriend now right?” And I had to repeatedly tell him for months I wasnt looking for commitment. Better for u to set expectations instead of accidentally finding urself in a new relationship u weren’t sure about. I wish u luck!
I can go on a date with a complete stranger and slowly get to know them over time but those first dates I wouldn’t consider them my bf/gf because they’re still someone I know virtually nothing about except surface level stuff. Personally I need to figure out how comfortable I am around a person before I start slapping labels on it. Some people prefer casual dates for fun and others are looking for a future spouse. Always better to talk about being a couple before assuming.
