Am I over thinkining?

Hey guys so I decided to give a guy another chance after 2 weeks of not chatting to him based on letting him know I was not feeling it at the moment. Any who he called Friday night out of the blue and told me he wanted me to give him another chance and so we talked for a while and I was like okay I will, than he has not text me once since Friday night not yesterday or today at all. This is confusing because we just talked on the phone on Friday and she shared how he missed me etc and I gave him another chance. What the heck? AM i thinking to much? Is he playing games? What are your thoughts?
