tell me how can I move on

I have so many explanations to give like there is a reason why I can't move on. I was not deeply in love infact I never knew him that much . I just liked the idea of him. The feeling I had when I was with him and the way he smiled upon seeing me. He told me that we will always be friends and that one day I was going to be his wife. He told me at 18 we will have my lobola and at 20 he will marry me. He told me that the surname I have is not mine but the one he has belongs to me. He called me sweetheart and told me candy dreams everytime I went to sleep. He looked into my eyes and managed to lie to me not once but a lot of times. I thought that we had the perfect love story even though it had not yet started. we had a million arguments and at the end of every argument I felt like the love we had grew stronger but it never did . He promised me the world like it was his to give and I believed every word of it and the more I realise the lies it burnt like a wound being added salt and chilli. Now I'm 18 and I nolonger remember his face. I'm almost 19 and he has not even engaged me infact I think he moved on. But I can't move on cause I'm still holding on to a life I dreamt about not reality.
