My oh has a little boy at 2 he's came with a cigarette burn on him and she tried to blame us after showing pictures of him before he left with no marks she then put it that it must have happened somewhere else then. We have just found out her new partner has a history of domestic violence, drug, alcohol and gambling problems and isn't allowed to see his little boy due to this and his ex has to carry a tracker and alarm due to him. He's been done with gbh against his own child by grabbing him by the leg and bruising his whole leg! He's been driving with my oh son in the car without a license and has been taking him to buy week etc! What do we do?! My oh can't sleep due to worry and he doesn't want anything to happen to his little boy
