BQ: In budding relationships, people sometimes try and pit one person against another to make themselves seem more valuable. What does God say about this?

A: "Wrath is fierce and anger is a flood, But who can stand before jealousy?" (Pro 27:4) If you check it out, Proverbs 6 mentions jealousy in the same manner, except it's associated with adultery. 

Jealousy in relationships is very unhealthy when it's created to manipulate someone, and it's considered even worse than anger and wrath. Don't use it as a tool or try to "play the game." Why begin a relationship with someone that's associated with failed marriages? Be open, honest, and loving instead.
