What's something romantic you did for your partner or ex partner?

The two things that come to mind that were small I actually didn't even think about that much. For my ex girlfriend I would write down important dates and her favorite foods and wine etc on my phone so I wouldn't forget and I'm told that's cute. And another time she was really stressed about a test she had so I drove up to the college and surprised her to give her a hug and motivation then I waited for her to be done and after I took her to get ice cream at the park.
