Send him your love letter in a card, text, or post (gift optional). If you’re in a long-distance relationship, you might consider texting or sending him birthday wishes over social media. If you want your letter to feel more intimate, you can handwrite it and send it in the mail.
- Birthday card: Handwrite the love letter and place it inside a birthday card for a personal touch.
- Text or social media post: Send him a short birthday message in a text when he wakes up so you’re the first thing he's thinking about, or surprise him with a social media birthday post.
- Pair with a gift: Consider giving him a birthday gift along with your love letter, like a personalized photo, a framed love letter, or a love letter blanket to keep him warm when you’re not around.
