I would say let him come to you, stop texting him for a bit and see if he hits you up. The waiting game is painful but it also shows you all you need to know, he may be telling you the truth and just was a bad weekend for him and he will ask you out. Or you may not hear from him again. Give him a couple weeks and if you hear nothing maybe it's time to let it go.

You don't have to give up but the ball is in his court. If he asks you to meet him and you are still interested, fine. In the meantime continue with your regular life, including dating other people.
