Why, was my supervisor teasing me about my coworker, who I haven't brought in months to her?

So, to make a long story. A few months back I confessed to my supervisor, about my suspiciousness of my coworker oh his behavior and how I felt that he was interested in me. Then, there was another time, I confessed and mentioned to her about my feelings for him and how I had a crush on him. So, I told her, please don't say anything to him. Fast forwarding, a few weeks afterwards. He started acting distance and not making very much conversation with me. To the point, when he did approach me, he started doing it in private. At 1st I really didn't understand it, I'm like that's weird and what is this a game he's playing. And, I notice when are supervisor isn't at work. He seeks our my attention the most! he talks talking to me and won't shut up. But, it's cute đŸ„°. But, when are supervisor is there, my gosh! Silence. But anyways, when they saw him and I together, they would tease me or be looking lol and smiling. lol đŸ€Ł. Like, this is so high school stuff WTF. So, months later. He to become distance and I was confused like OH Ok cool f it. So I decided that I was going to move on and let it go. So I had to go back, and pretend like I wasn't interested in him. But fast forwarding up to today. I haven't brought up this guy to her months. And when I was at work this morning, and vacuum cleaning the floors, a rock got stuck in it. And, it almost like a shooting sound. So, she said: oh no. I'm going to get... blank.. blank.. he's going to come and get you. She said, he going to come get me, for breaking another vacuum cleaner. But remind you guys, I haven't mentioned anything else about him. So what was her reasoning? I only said. No! it's not broke. Wtf is deal? Read updates to question below! đŸ‘‡đŸŸ

Like, what is she trying to do. Because she never said, that him and I couldn't talk. He's the one, started acting weird with me, around her others coworkers. But, she was acting some type of way, like she didn't want him and I to connect. But now, she's saying that he's going to come and get me a vacuum cleaner. I wonder, if he Said something or was she trying to see my reaction?
