I still love my ex

this is really complicated. so I have this childhood friend, let’s call him justin. we were bestfriends since I cant remeber when. but I moved and we stayed connected through texting. then one day, I just realized that I love him. and he told me he loves me too. so he became my boyfriend. then,my dad knew about it. I forgot that I wasnt allowed to have a boyfriend cause I was so madly inlove with justin that I just forgot about it. so I told justin that my dad wanted us to break up. he said it was ok with him if we break up. after a couple of months, he started acting different. he told me he was so hurt by what happened to us, and that he thinks he’ll die because of it. of course I was worried, and I kept telling him to wait for me. but he wont listen, he stopped replying to my messages and deleted me on his friends list in friendster. and now I’m worried about another thing. I met this girl named ledi in friendster. she goes to school next to the school justin goes to. and I told her about my problem. but I didnt tell her my ex’s name. and, she said she’ll help me with it. then when I finally told her, she told me she has a crush on justin. and she told me not to get mad at her for that. well I’m not, but I’m just worried cause I was hoping justin wont replace me with someone. but I have this feeling that he will because ledi will be there to comfort him and I’mscared they might end up together..please help me…I really need answers that can help me with it…
