n. A relationship between two people that is more than a friendship, but less than a romance.
For all the boyfriends that were never really my boyfriend, past hookups and their mealy scars of things left unsaid, there was now a clever umbrella term: situationships. And getting involved in a situationship might be the worst thing you can do to yourself.

I have a disconcerting habit of keeping some people around longer than I should. So it’s sadly no surprise that I stayed in a “situationship” that looked like a committed relationship, but wasn’t, for way too long.
What’s a situationship? It feels like a relationship, and to everyone else it may seem like one, but it’s not.
