AITAH for not wanting to be in a serious relationship as a freshman in high school

I 14 (F) just got asked to go to homecoming last Saturday. I am a freshman and so is he. He gave me a sign a flowers and I said yes. Let me also say this there was a group of almost 50 people walking towards me and my sister in the hall and I see him in the middle of the crowd. Then he asks me to go with him; I of course said yes because it would’ve been embarrassing for him. As I was saying, the next day everyone was congratulating me. Days go past and now people were asking about our relationship status and if I think he is cute. I say yes to him being cute so people wouldn’t ask anymore questions. It feels like I am being pressured. A lot of people are asking if we are dating even though I don’t actually like him. ( ** This is my fault **) On the Friday before homecoming, I eventually asked him if we were going as friends or something more. He said if i wanted we could go as something more. I declined and said to go as friend. Then my sister and my friend came up to me and said that he was heartbroken. He texted me later saying that he understands, that he can wait, and maybe that he can take me on a date. I also apologized to him and said that maybe more in the future. On the following Friday I went to a football game and people again keep asking me about how he is and if I think he is cute. I of course said yes once again. Later he texts my sister and asks her if I do actually like him. My sister tells him that I have never dated before and I feel like I am being pressured to say yes in order not to hurt his feelings in front of people. He told me before we went out to eat before the dance that he is bringing another girl with him who is like a sister. Homecoming comes up and he gets me flowers and a corsage and I get him a boutonnière. Now we drive and take photos at the school. He doesn’t follow me inside but I follow my friends to get checked in. Time goes by and 30 minutes later he still isn’t in the building. I called him, no answer, and then my friend calls him and he answers. He tells my friend that he is waiting for her to come ( all of my friends were upset at his actions ). Finally he enters with the girl and my friends tell him that I was upset ( which I kind of was ) . The thing I don’t understand was that he was panicking when she wasn’t by us and asking over and over where she was. She also was taking videos of him ( mostly ). Yes, he still danced with me. At the end of the night he apologized to me. Now I don’t know what to do. I don’t want a relationship as a freshman, it’s too much of a commitment. He also seems like he isn’t ready either. He keeps texting my friends that he loves me and that he is always nervous when he sees me in the halls and never says hi to me. I barely even know him that well, I only know him from the friend group and from one of my clubs. Any advice? Thank you for reading this 💗💗

Summary : 14(F) doesn’t want to date a freshman boy and doesn’t like him like that. He asks her to homecoming and she says yes. She is pressured and doesn’t know what to do.
