So from my understanding she will try to get a comfort test if you made her feel like shit, she wants to make sure you won't leave her for someone else etc and you should answer with something along the lines of "I don't need anyone else right now".

A shit test is more aggressive and you have to let her know you have other options kind of shit.

But there was a thread right now were a girl was saying something along the lines of "I'm not sure about us" so the guy broke up, people in the comments claiming it was a comfort test and not a shit test.

How do you tell the difference in such situations?
