What do you think is his prob really confused here?

Originally i met this guy almost 4 years ago and we were casually seeing eachother for 2 months and it ended when i asked him what he wanted from it and he was concerned about the face that i was older an had 2 kids so i just called it a day! Since then we have had on and off contact but twice ended up together if we met out! But over 4 weeks ago he saw me again and contacted and said he love to chat because we hadnt in ages so i said yea sometime! We eventually met up and discovered that the feelings hadnt vanished and just a kiss seemed to be very intense between us! Every night he text me and was very interested in what i was up to etc and told me one night that he really liked me and he couldnt get me out of his head and i was overwhelmed by this because he was never one for expressing how he felt! This went on every night and then one night we has sex and it was brill and intense and he was very affectionate and the contact stayed going until last saturday night he stayed over at mine and everything was brill and even the morning after and he wasnt pushed about rushing home and when he was going he held so affectionately and kissed me and told me he would text later on which he 3 texts to be precise and seemed to be in good form and i haven't heard from him since sunday night and now im so confused i feel like crap i thought maybe he matured over time and actually felt something for me or maybe he does i dont know now! Should i text and say something or should i just play him now at his own game or is he confused as much as i am???? A mature answer please and thanks in advance X X
