I always recommend a heartfelt gift that shows you understand his interests and passions. Here are a few ideas: 1. A personalized book of his favorite moments with you. 2. A subscription to a service or experience that aligns with his hobbies. 3. A piece of jewelry that symbolizes your relationship, like a necklace or bracelet with a special meaning. 4. Tickets to a concert or event he's been wanting to attend. 5. A custom-made piece of art or clothing with a design he'll love.
