.... what now

I left my boyfriend of 3 years today. We are not for eachother.... we treat eachother so poorly and it’s not good for us. I take half of the blame. I’m just lonely... super lonely... I’m sitting in our apartment by myself and look down the hallway at our bed. He should be home later but I’m super down at the thought of sleeping by myself for now on. For moving all my stuff out.... how will I ever get used to this? It’s like a part of me is gone because we were in this routine everyday & now it’s over. I shouldn’t be sad, I was the one who decided to let go. It’s just a sad situation... I’m not even crying, I’m just numb. How do I move past this?.. I have a horrible feeling it’ll interrupt my daily life and job life. Uhg... help
