Good for you G.....to the guy that didn't text all week I would just let him know that you are busy this weekend however that you might have free time next weekend so he can reach out if he wants to make a date. Then leave it alone and let him do all the work.
As far as the other dude goes, I made a date with the Dr. 2 days ahead of time with a specific time and place then didn't call her for 2 days. She reached out 1 more before the date to confirm if we were still on.
If this dude has not made specific plans with you then when he reaches out I would just let him know that something came up and since you had no specific plans made you assumed the date was off. However he can try again maybe next weekend and put the ball right back in his court.
I guess what I am saying is don't be easy and make the dates for them. Make them do the work to court you and ask you out. But your not just sitting around waiting......F that.
This is if you even want to still go out. If it was me and a girl did that to me and I was interested in her I would still ask her out if she went dark on me for several days.
