just need some tips on love

i am 13 and i have a huge crush on my ex boyfriend. what do i do?!?!?!??!

*he may or may not have been my first kiss*

we dated for four months and he dumped me. I don’t want to date him again, but i’m not sure if i should tell him if i like him? Sometimes he tells me i love you (joking way) and he told me he still likes me but at the same time he also told me he doesn’t like me. I’m so torn. I am so in love with him though!!!
