I need a boys opinion, help please!?

okay so i've been talking to this boy for almost a week now (yes, i know thats not a long time) but everythings been going good up until today. for the past 5 days that we've been talking he texted me first. well today he didnt so i decided to text him. he replied and we talked for a little but it wasnt like normal (maybe im worrying myself too much). but the other day he was texting me while he was at work and was making an effort to actually text me.he came over two days ago and kissed me too. well hes at work now and he isnt making an effort to text me. maybe im just worrying too much (which i ALWAYS do) but i dont want me and him to be done talking so soon. opinions?
