I really feel for you, if you can/want to report it, I just hope social services and the police are better in your area than mine (northants). My step sis is abused by her fella, they have 4 kids 3 and under. Its suspected that the 3 eldest (all girls) have been touch by his friends. The 3 yr old speaks in detail of whats happened. No 3yr would know such things unless it happened. Anyway nothing has happened, police won't take the childs word for it. She wont leave him (has had various handouts/chances to). Social services said they couldnt live with the father till he had anger managment, drug therapy (he takes all benefit money for food clothe etc, spends on drugs- neither work) he never had any such therapy and then social services arranged for the deposit for a place for them ALL to live together. Even though they know he tells the children he doesn't love them/want them and his daughter is a lying little f***er when its comes to his friends.
So even when you ask for help from the right people, sometimes nothing happens. Good luck though x x
