I need advice 10 pts?

I've known this guy for about a month. We've been texting and calling back and for. I met up with him last week and agre we hung out he called me like 20 mins later. Obviously the interest is there but he hasn't texted me all weekend. Last weekend it took me to text him when during the week it's mostly him. I know he has work today but that shouldn't prevent him from talking to me since I've spoken to him at work before. Is he waiting for me? Advice please
