I like this Reddit author’s approach to dating:
… these dates happens in a span of 1~3 months. NOT 1~3 weeks, so DONT rush it …
if she rejects you, be cool just say ‘i hope we can still be friends’ and actually DO IT.
It feels like a much more natural, low-pressure way of getting to know someone and it isn’t specific to college. I think it’d work especially well after meeting someone from online dating.
