Here's why:
* "Infinity" is an abstract concept. While it's a powerful image, it's difficult to quantify or truly express in a literal sense.
* "Beyond" is vague. What does it mean to love someone "beyond infinity"? It's an overly dramatic way to express love.
Here are some alternatives that might be more effective:
* "I love you more than words can say." This is a classic and heartfelt expression.
* "My love for you is boundless." This uses a more concrete term ("boundless") while still conveying a sense of deep affection.
* "I will always love you." This is a simple but powerful declaration of everlasting love.
Ultimately, the best way to express your love is to find words that resonate with you and feel authentic.
