I met a guy and there was a great connection. We hung out a couple of times. Eventually he’d pick a day to hang out again and when the day comes I don’t hear from him. This happened once more. Then he texted me, I replied a couple hours later and never heard from him. Over two weeks have gone by and all of a sudden he just texted me, “Hey”. How do I respond, should I respond, what should I think? Thanks!
