Some comments here make me think that sex is the only interesting thing posters can offer to a guy lol that is why they try to keep it to themselves as long as they can hahaah. All is pretty clear: if they guy wanted only sex he would be gone sooner or later. If he is interested in you/relationship, he will stay. I am not sure why you stopped communication with him, but it is Thursday, so maybe you can text him and ask if he is free on Saturday?
