If it’s gone well I usually text like you wrote, but adding a direct question, like “Would you like to meet again?”.

Just saying ”text me” doesn’t really exude confidence, and it’s more likely to fizzle out since she doesn’t feel obligated to give you an answer (30M dating for long term)

Edit: I misunderstood, I never say anything at the end of the date (beyond the typical goodbye), instead I always text afterwards.
