I been through a constant battle with my ex and his mother the done nothing but cause me problems. He cheated on me three times one was while I was pregnant with our baby and he gave me clymidia. I stuck by him while he was in the army and I always been main parent for our daughter.i love my little girl so much and do anything for her. Me ex Harrassed me to point he took all the furniture out of my house and him and his mum called social services on me.we been to court once and had shared custody where he has my daughter over weekend but even with this he couldn't stick to it he now taken my daughter and won't let me see or speak to her.i tried social services and the piece both won't do anything as he on her birth certificate I applying to go to court for full custody but I'm scared they won't give it as she now in school which I he no idea where she is even though her dad took her out of nursery.
