Why does he say he’s interested?

So I’ve been dating a guy that I work with but he’s in a different department. Things were going really good up until he stopped suddenly texting me outside of work. I do see him from time to time at work but it’s hard because we’re both busy. He’s divorced has kids and tells me he’s been so crazy busy that it’s not fair to me. I get it he’s a single dad but he showed effort in the beginning too. I’ve told him many times we don’t have to continue this and he keeps telling me he’s still interested. We’re supposed to have dinner tomorrow night but he hasn’t told me where we’re going and I’m tired of chasing him at work and always texting him. He still flirts with me at work and stuff but I don’t get the non communication outside of work. Plus I haven’t even been to his place and we don’t get together on the weekends.
