LOL I have another guy question??

Yes, I know I have lately made this sight my go to for men advice haha. SO I have been on four dates with this guy and everything is great when we hangout but we don't text that much because we are both busy, anywho sometimes I feel like he is not into me because he doesn't seem that affectionate, but he did tell me the other day las time we hung out, he said" he has been a lil concerned in why I like him.?" I don't know I feel sometimes like hes disconnected at times. Anywho does is he not really into me or am I overeacting?
