Am I Dumb?

So I'm 15 going to be 16 November 8th and I was dating this boy that I really like (we dated last year but due to certain things we broke up), I was thinking about maybe giving him my virginity. After a while things started to happen and we started to argue a lot so homecoming was last Friday it was wonderful I had an amazing time w. him. Monday came around he felt different and like he had to worry about football and his work so he couldn't worry about me too (what type of shit is that) but we broke up. What he was saying didn't make sense but I really don't wanna go to school I have 3 classes w. him (I went yesterday tho) but yesterday I wanted to break down seeing him doing fine while I'm heart broken hurts I had all types of mixed emotions yesterday (let's remind you I'm on my monthly so its horrible asf). He asked me to go to his game so I did I stayed a little while but it was raining hard asf so I left. He saw me w. my boy bestfriend and gave me a hug in my head I'm Like "No Fuck You!!!". But the point of the story is my brother asked me was I thinking about giving him my virginity and I said Yea he told me "don't because he's still has a little boy mind and all he's going to do is fuck it up". I'm glad I didn't tho because I was thinking about it heavily to give it to him on my birthday but he showed me why I shouldn't.
