How do u get over someone?

Me & my husband spilt up, hefiling for divorce... there r issues on both sides.... I still have feelings for him but hate him too... I am having regular therapy sessions too... but is there a 'proper' way to grieve? I don't really have any friends anymore, well no close friends & my family do listen but they don't listen as a friend... gets me down & feel ever so much more alone... hard trying to stand on my own feet...
