Lonely 😩

So it's been just over 2 weeks since I broke up with my boyfriend and to be honest I still cry myself to sleep at night because I miss him and the good parts of the relationship but I just wasn't happy and he wasn't willing to compromise so that was that. What can I do to remedy this? I know it will take time but I still feel like it happened yesterday and it's messing with my head, especially as I'm alone with my thoughts.. It makes me want to get him back
