Connor Beaton explains why women test men in relationships: to check if they're truly monogamous and won't turn violent, and to assess whether they'd be safe fathers. Women are essentially screening for safety and stability before deeper commitment.

Women test men, or women punish men that they like because they are testing for safety. You might notice that women sometimes will test you to see, can they provoke your anger? Can they get a rise out of you? Can they get you to become reactive? Why do they do that? They're doing that for a number of reasons. First and foremost, they're doing that to see, am I safe in this relationship? And is my idea that we are in a monogamous relationship true? Secondly, she'll be testing for emotional safety. So women will oftentimes sometimes unconsciously test, especially when the relationship is starting to get into a more serious place. They will unconsciously test to see is this man safe to have children with? Because if he loses his temper with me and blows up all the time and is violent or very aggressive, then the likelihood that he's going to do that with children is very, very high.
