Never Responds

Emma
So I've been dating this guy for 2 months and when we first started dating he text me back immediately (granted we were on winter break so he didn't have any classes or University stuff to take care of). However, it really pisses me off that now that we are back on campus he never responds to me. He'll text me and I respond immediately and then he won't text back. He'll open my snaps, and watch my story but doesn't feel the need to send me a quick text. It also bothers me because I know that when I am with him he has his phone in his hand all of the time and he answers it when I am with him but never when I text him. I know he's super involved on campus but damn you can't find time to respond to a text. What do you guys think? Is this something I should continue to worry about or something that I am thinking too deeply about??
