My daughter is 17 and her boyfriend is 19. They have been together for over a year, on and off. He used to stay here but there were often issues and dramas. He attempted to strangle himself in front of my daughter when she said that she was ending the relationship. I told him that he needed help and that doing what he did was emotional abuse and controlling behaviour. They got back together after a while and I met with him, with my daughter to discuss my concerns etc and spoke about how unhealthy their relationship was etc. They were determined however to stay together. A few weeks after this my daughter then took an overdose, is now under CAMHS and has had her first counselling session. Her boyfriend was supportive and he started to come around again, although my partner wasn't happy, he went along with it. Then the boyfriend then started messaging other girls and they split up again. This time he jumped in front of a lorry in front of my daughter and said some horrible things. I phoned the police. Now they are back together again and because we were so angry with him, we said we did not want him near the house. This is where another problem arises. They spent three nights sleeping in his car. My main priority is my daughter's safety, therefore I need her at home. I spoke with her CAMHS worker and she has said that it is a co dependent relationship. She suggested a meeting with all the parents to see if we can maybe come to agreement and share where they stay. I tried this but was unsuccessful with his parents and she is not talking to her Dad. I am thinking of suggesting to my daughter and her boyfriend that they stay here an agreed number of nights, if they agree to spend the rest of the time in their own homes. My partner, will not be happy at all about this suggestion as he was adamant the boyfriend would never step foot in the house again, but I really don't know what else to do!
