Is he emotionally unavailable, not as interested, or takin it slow?

Question

I met this guy on a dating app. He seemed nice and was open that he just got off a relationship, so he would wanna be friends or casual. Of course I said it’s best to be friends since I would prefer dating. We were cool, he seemed fun and chill. He also has a baby. Slowly I noticed he seemed really sweet & I still find him attractive. We slightly flirted and I asked if he’s open to be more than just friends since he calls me princess and we had a bit deep conversations. He agreed to be open & mentioned he hasn’t try dating before with a baby. I said we can just take it one step at a time & I don’t mind the baby being there in some dates. He texted me morning the next day, but I noticed he doesn’t really message me a lot.. it’s still very spread out either morning, some hours, noon or evening or later time when I know it’s supposed to be his days off.. also yesterday he made a comment on my story of my co worker liking me that was sweet or cute what he did for me. I was like I’m not used to guys seeming excited about that since most prolly isn’t and maybe he’s not really interested then lol. He said he just didn’t wanna step in my toes and not sure what we had.. but he said he’s not thrilled of it. Anyways I don't know his messages isn’t really progressing today… made me wonder if he’s just not that into me, taking it slow or just not emotionally available? I don't know what to do.

He did asked a few times to hang out but we have diff days off… his is w-Fri and mines Saturday which he said it’s the busiest for him… he’s a bar tender… he didn’t really say much after it.. I don't know if he’s that busy or just don’t wanna make Saturday open for me 😟 abit disappointing since I felt like we connected well….
