I hooked up with this guy I have liked for a while last friday. It is now Sunday and he has not texted me or tried to make any communication. I dont want him to think I like him even though i do.
should i wait for him to text me, or should i text him first?

Wait a few years until you mature into an emotionally honest woman who has enough self respect not to play silly mind games with her cell phone, and then call him.
