Formal and Poetic Alternatives

• Bosom Friend: An older, more poetic term that suggests a friend held close to the heart, implying a deep, intimate, and loving connection.
• Platonic Soulmate: A powerful, modern phrase that perfectly describes a non-romantic relationship where two people feel destined to be connected, sharing a profound spiritual and emotional bond.
• Anchor: A metaphorical term for a friend who provides stability, security, and grounding in times of trouble.
• Ally: Emphasizes the friend's role as a supporter and partner, especially during challenges or conflicts.
• Comrade: While often associated with military or political groups, it can be used to signify a loyal partner who has shared a long struggle or journey with you.

Using terms like *confidant* or *platonic soulmate* adds a layer of sophistication and emotional weight to your expression, making the compliment feel more significant and memorable.
