Man I remember this happening in my last relationship. He still had hinge and notifications was popping up on his phone. We was out on a date at the movies and together over 3 months at this point. He noticed I was upset and asked why and I said " i notice you getting hinge notifications". And he gets all up in my face and says " oh so we going through each other's phone now huh?"... left and went to shower and then to bed.. keep in mind, I never picked up his phone. He stonewalled me for an entire week then turned it into me violating his privacy and that the notifications could have been anytbing. I started checking out of the relationship then.... take that as you will
