My ex is moving in with his girlfriend?

It makes me feel so sad, and i don't know why. I don't want to be with him though.
I feel like he's moving on and being happy and im stuck here hurt from our relationship still, its been nearly a 10months now
Will i ever get over this?, iv tried to meet over people but i find it hard as i have the children all the time and never really get much free time.
Everytime im down i think about him. It makes me think im only worth that relationship (which wasn't healthy for either of us).
Im sick of crying, im sick of fighting with myself. Im scared to put myself out there and be hurt. Will this ever be different, or is this me for the rest of my life?
