Purposely hurt me or trying to get a reaction?

So I have been flirting with this guy. A lot of sexing, etc. We do not live near each other but we were going to try to hook up. We got in a small tiff and he then turned around and started posting all of these pictures of him with this other girl. (Since the inception of our flirtation he has not posted anything like that). It seemed so very uncharacteristic. What the fuck? Is he just trying to get in the last dig? Do I ignore it or what should I do?
