10 yrs ago i went through the same thing as your going through now,my ex was so nasty,that when i did find someone nice my daughter who was 16 at the time went to the extreame of blackmailing me against him,saying if i didnt get her this and didnt let her do this she would run back and tell my ex lies just so he would still give me greif,and for a while i used to give into her as i was so scared of him,i spent 9yrs of hell.but i decided one day that enough was enough,i told her to get out,and she was only 16yrs old,but it was the best thing i did.i cried a few weeks ,not knowing who she was with,and what she was doing,but it didnt take long when she came round and said sorry for hurting me,my daughter,and me get on great,i love her to bits and now shes a big women,and stands on her own two feet,please stand strong and be cruel to be kind .you will both be better for it in the end.xx
