Yes, Ester is made for Ben. She's an alien, Ben can become a plethora of aliens. Betraying her would be a complete destruction of their bond. I notice that she is appearing in Catfight, which could be the episode where Ben and Ester go on an on-screen date and start their relationship, presumably at the end of the episode.
