I would recommend The Five Love Languages: The Secret to Love That Lasts by Gary Chapman. This is a great book to discover your love language. The five love languages include:
1. Words of Affirmation
2. Quality Time
3. Receiving Gifts
4. Acts of Service
5. Physical Touch
I would suggest you read this book even if you are not in a relationship, as this information pertains to all relationships in fully understanding your style in how you give and receive love.
