O'Shea recommends this format as your inspiration. Here's how to let it guide you:
Past: Write about when you first met or — even better — the moment you fell in love with them or your love deepened.
Present: Share what the person brings to your everyday life. O'Shea suggests calling attention the little things you love about them (like how she looks when sipping her coffee or how he always has the perfect reaction gif for every situation).
Future: Talk about things you're excited to do (travel, start a family) and your shared dreams. According to O'Shea, this communicates "I'm here and I want to be here for a long time."
