What does it mean if a guy is weird about admitting his feelings?

I was out with one of my colleagues and we were both a bit drunk. I told him that I have feelings for him and I asked him several times if he felt the same way. He kept saying “you’re a lovely person”

Eventually, he said he did like me back. What does his reluctance mean?
