How long does it take to stop hurting?

Yesterday I broke up with my everything.

My childs father

My highschool sweet heart

The man I planned to marry

The only man I've ever had sex with.

The man I sadly still love and I'm crying while I write this. He's hit me cheated hurt me but saying we are over hurts more then anything. I don't know why I love him still but I do I want to run back but I know i can't but this shit physically hurts I can't breathe my head hurts I cry myself to sleep I just want him to love me but he hurt me😭 I don't know what to do or how to act anymore I feel so broken
