Why did he say he would text me but didn't?

My crush and i had set a date to go on a date and i asked him to let me know asap what time because i need to work that day. Its been 2 WEEKS. We are supposed to go on our date in 4 2 days. He still hasn't texted me. I dont wanna seem like im running after him but im getting annoyed that i can't make concrete plans for that day. Should i text him and ask whats up? At this point i dont even know if the date going to even happen. I've posted social media updates which he has seen in hopes of him remembering to text me... NOTHING. What to do?
