Cereal Monogamist 

A person who eats the same cereal every day through the course of several boxes.

Phil: "Hey Kara, what do you want for breakfast?"
Kara: "I've been into those bran flakes for the last several weeks and I see no need to change."

That's a cereal monogamist.

Serial Monogamist 

Someone who jumps from one relationship immediately into another one.

Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.

Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.

Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.

Person 2: No, he's a serial monogamist...
