I've met a few girls on Tinder recently who, after second or third dates without sleeping with them, have said that they decided to delete Tinder and don't think they can handle casual relationships that aren't leading to something serious.

Therefore they don't want to keep seeing me because at some point I told them I probably wasn't looking for anything overly serious.

Is it better to just say that I might be looking for something serious? It's true at first, but with most girls after a date or two I have some sense that I'm not interested in a super-long-term relationship with these girls.
