DO: ASK HER ON A LAST-MINUTE DATE
On a random weekday with perfect weather, see if she's up for outdoor margaritas after work. Or if you’re heading on a bike ride on a Saturday, see if she can come along. Inviting her to do the day-to-day stuff you already had planned makes it clear that it’s not going to be some over-the-top event, and it'll make her happy that you want to see her just because.
But to be clear, this does not mean you should text her at midnight to see if she's out and about; that'll just make her feel like a booty call.
