My girlfriend brought over dinner for me out of the blue and afterwards we were cuddling so I tried to make an advance on her and she let me grab her boobs and ass. When I tried to go further she got mad all of a sudden saying we had already had sex too much (4 times this past weekend) and decided to leave. I let her leave without saying anything but bye and kissing her on the cheek like it was normal and didn't try to keep her because I knew it was a shit test. She just got home and sent me a text "You made me feel uncomfortable earlier." How do I respond to this?

Update: I responded "You should of talked to me about it before you left" Then she responded trying to insult me "Sometimes you get horny and irritated and I didn't want to see that play out".
