What does it mean to fall in love with a wild horse and have no grassland at home?

To put it simply, although I like this free-spirited horse. But there is no grassland suitable for its development at home, and it can't give it a better life at all.

Explain in the workplace, which means: although I appreciate this person very much, I would like to have more contact with him. But he is too capable and ambitious. The pattern here is too small for him. I am more afraid of delaying his development and affecting his future. I can only give up reluctantly.

Personally, if you say this, it means that although you are excellent and I like you very much, you are not my type.
