I think Mandy liked Billy that he was able to ground her to reality. That element in her life she can't 100% control, and doesn't want to. She does take a personal ownership in their relationship is enough for her.
>Episode where Billy mom de-ages, we can see Mandy get jellyI think Billy sees Mandy more of a boss than romantic interest. I think a lot of people think Billy is too dumb to understand love, but he's chosen other girls in the show before two Indian sisters for Valentine's dance and an alien he wanted to marry.
There is one episode I always find curious where Mandy orders Billy and says "Thank you" to which Billy takes as an insult and straight up quits. To which Mandy replaces him with a doppelganger, causing Billy to get rid of him and go back to being Mandy stooge monkey
