When it comes to competition and envy in relationships/with other people, what types/IM could this be? I would assume Se valuing types are more prone to this.

For example, I've little doubt I'm Se valuing, and overall consider myself pretty healthy despite whatever type I am... but my unhealthy side stems from this stuff. Especially if any romantic interest is involved. Or even easily get envious of friends. A bit "catty", if you will.

I'll give specific examples soon, as I'm about to head to work, but I was curious and thought it would spark a decent discussion.
