getting over an ex🤔

Nia

i recently moved from philadelphia to houston over the summer and was in a relationship. he was my first everything and i thought it was the end of the world when i moved. i’m still in high school and i had to leave all my friends and my boyfriend. i really thought that maybe we could be together one day in a year when we graduate but he’s moved on☹️he has a full on girl friend now and i’m still trying to get over him. how do i do that? i feel like every time i try to move on, i start to compare every little thing to him and i hate it!! i just was to move on and stop thinking about him because it hurts to even think of the fact that he’s with somebody else. any advice?
