I always see the advice “give them the same energy they give you. If they’re flakey you be flakey. If they take an hour to respond you take 2 hours to respond.”

This is terrible advice and simply a waste of time. You give the energy you give and if they don’t match it to your liking...don’t give less, give nothing.

Move on to another girl who’s going to be worth your time and will actually put in effort
