When a new relationship feels right, how do you keep a healthy pace?

An autistic friend of mine recently met someone who makes dating feel comfortable and easy. They’ve only known each other for a few weeks, but they talk daily and are already exclusive. She’s excited, but the intensity makes her nervous. I reminded her that feelings can develop quickly while major commitments can still wait. They can enjoy the relationship while keeping their routines, friendships, personal space, and honest communication. For autistic people who have experienced a fast connection, how did you enjoy it without rushing?
