break up💔

It's been a week since I broke up with my boyfriend and I honestly feel like it's just "killing" me inside. I broke up with him because there was no effort from his side anymore, I would have to beg for his attention because he'd be constantly playing this computer game or watching some series and we would never go out together anymore. One thing that really annoyed me was that he'd always complain that I'd look after my baby sisters too much... yes I looked after them but only because I wanted to help my mum. She's done everything for me so I could have a better life so what was the problem of me helping my mum? But because he was really spoilt by his foster mum he never had to do anything. He used to tell me that when I turn 18 and start going clubbing our relationship wouldn't last...which I found sad because he started drinking and going out when he was 14/15 in Brazil, so he started having fun when he was young but I've never got the chance to do that. Not even house parties because my parents are kinda strict because they know what happens in parties. Also he'd never let me check his phone but he would always check mine but I was also afraid to check his phone in case I saw something I wouldn't want to see which was stupid of me. So yeah, all of this led me to break up with him but I still love him and it was so hard to do it but I thought it was for the best but now I miss him so damn much and just want to cry every time I think about him. This probably sounds all stupid but I just don't know what to do and he blocked me on everything after we broke up💔💔😞😢
