So to give you a little background, I have been talking to this guy on Tinder for roughly a month now. We would talk everyday and our conversations were good. We've had talks about how neither one of us are really seeing anyone and haven't dated much recently. We finally met last week and he ended up staying the night and we slept together (mistake I know)!!!!!! Neither one of us were planning on that to happen, but it did. It was good and we talked afterwards and things seemed light and fun. The next day, he texted me in the evening just basically saying “hey what’s up??” and we talked back and forth a little, but I noticed his texts were shorter than usual. He continues to respond back and forth to me, but should I be taking the hint he isn’t interested? I have since stopped responding....but I'm not sure if I should reach out to see what's going on. If he's not interested, why would he have even reached out?
