Anxious dater - can't read my love interest's signals?

A guy I work with asked me out on a date. I gave him my number on Monday, he asked me to hang out the same night.

We had a terrible first date - I was unintentionally mean to him, we argued intensely, and then we ended up having a really cool conversation before I went home. He asked me to hang out the next day, and we did.

The next night seemed to go really well. We talked, cuddled, and he said we should hang out more before I dropped him off.

He wasn't in at work the next day, I sent him a text to inquire about the tattoo work he was getting done, no response. I brushed it off, and at work on Thursday, I stopped by his desk (interested in the new tattoo) and I felt like he didn't want to see me AT ALL. He was in the middle of a phone call, but he barely looked at me!

So I chilled out last night, didn't say hi to him at work Friday, but I really want to see him again.

He said he doesn't like clingy women and likes space, but I can't tell if he wants room or doesn't want me. Help!
