Why is Aeneas not supposed to love Dido?

Aeneas is not supposed to love Dido because his destiny is to found Rome, a mission ordained by the gods. His love for Dido distracts him from this divine purpose and could jeopardize the fate of his people. Additionally, the gods, particularly Jupiter, have made it clear that Aeneas must prioritize his journey over personal desires, making his relationship with Dido a forbidden attachment that ultimately leads to tragedy.
