I gave him my number?

So i like this guy i work beside, its hard to try and get a conversation going because we work different shifts in different parts of the building. I tried to slip him my number myself but kept getting distracted so i got my colleague to do it. The guy text me to say thanks for my number and I asked him if he wanted to go for a coffee, he said he would but was just out of something and wasn't quite to start dating again yet, he asked for a raincheck & I said okay thats fair, I understand, give me call when you want to go out. When we see/pass each other we smile, say hello & nod to each orher. Its been a couple of months and i'm wondering if am wasting my time.

I gave him my number?
