My boyfriend left me

My boyfriend left me because he’s struggling and feels like he needs to fix his life, and to do that, he wants to be alone. I still love him very much. He left me a week ago, and ever since then, my life has been getting worse and worse. I can’t imagine starting over. I don’t want to meet someone else, and I don’t want to be alone either. I don’t want to accept that my life from now on will be without him. I’m extremely sad and still in denial. Part of me keeps hoping that one day he’ll come back, even though I know that’s probably not going to happen. I don’t know how to move forward. Right now, I don’t believe I’ll be able to get through this.
