lonely and sad

I broke up with my long time boyfriend a couple hours ago. (it was well past time for it, toxic relationship) and even though I know I did the right thing..... I kind of sort of miss him. i was about to go to bed and realized, it's been years since I slept in a bed alone.... I don't know what to do. I think I just miss him because I'm not gonna have his arms around me tonight... what to do!?
