Red flag?

Hi there, so I wanted your opinion..

I started lately dating a guy who is super handsome, to be honest im kind of chubby and I didn’t think I could pull someone like him, but apparently I did without even knowing..

Anyways he took me out on 3 dates so far, but I noticed he doesn’t really like to text nor to call..

He would rarely take his phone and text to tell me he missed me..

yet when we are together he is very loving, gentleman, and also nasty.. he shows me he is really attracted to me which makes me feel more confident.. i am someone who likes to communicate, i understand he works full time job( so do I) and goes to college as well.. but u really need to communicate.. he is also weird, , very introvert, small cercle.. very hot and he knows it.. lately i started just acting like him.. i d barely text him as well
