I finally called him out for flirting and he acted this way?

Helloeriss01
Last week my coworker said he was happy to see me that day.
He also told me that I smelled really good and asked if it was me. I sit at the front and he works in the kitchen.
I have seen him compliment other coworkers like their nails and dress but more brotherly.
He also hugged one who’s in her 40s because she had something going on with her mom but it seemed brotherly lol.
I went to give him a package and I told him I had been looking for him and he was like “we’re you?” Kinda flirty.
He asked if I had plans for the weekend on Friday and I told him I was hanging with my dad for Father’s Day. He said he was going to the mountains with his girlfriend and her dad and he took forever to say girlfriend lol.
After that convo we both kept saying “yeah” and “cool” and he lingered and there was a weird strong sexual vibe.
There was a bug and it scared me and he tried to tease me and fake scare me by pretending the bug was near me.
He had to train a new girl and they kept coming to my area. I saw them but was already rushing to go home. She came in the bathroom and when I came out my coworker was standing there and asked “what was that” but said it was because I was rushing. He followed me back out and told me bye.
Yesterday I was looking down and he was approaching from far away and he was like “hey Kathy” and he thought I was my other coworker who sits near me. we have similar hair and stuff and I was looking down. I looked up when he said this and laughed and he was like “day one without my contact lenses. I was about to say Kathy looks great today.” And he was talking about me.
Later he was like “hey Kathy” because he was teasing me. He knows I’m seeing someone.
Today when I got in he came over and said good morning. He was blushing hard and it got quiet again and I laughed and he asked “what?” And I told him it was awkward and he just said “ok” then looked at me then walked away. Why? Lol. He still came near me throughout the day. Why’d he say ok?
