Option 1 (More Literal):
"I love him so much, but I love the way..."
Option 2 (More Poetic):
"My love for him is deep, but I adore the way..."
Option 3 (More Direct):
"I love him so much, and I love how..."
You would then need to complete the sentence by adding the specific way the person loves the other.
For example:
* Option 1: "I love him so much, but I love the way he makes me laugh."
* Option 2: "My love for him is deep, but I adore the way his eyes light up when he smiles."
* Option 3: "I love him so much, and I love how he always knows what to say."
Ultimately, the best translation will depend on the specific context and the emotions you want to convey.
