I am having a lot of problems with my 15 year olds girlfriend. He went out with her last year for 3 months and then I caught her on facebook saying things to him like 'i wish i could go and get raped just to get your attention etc'. She has a bad relationship with her mother and hates her sister, her sister seems to get all the attention as she is a dancer and gets lots of money and attention lavished on her. She kept on at him every single day to come down and see her which in turn made him lash out at me because i said no. she lives 10 miles away so i would need to take him. school nights are a complete no no. i made him dump her in Nov and everything was fine until last week. i found out he was seeing her again and i told him to stop it. yesterday he said he was going out with his friends which was fine, but then his friends called for him and i said hes supposed to be out with you and they said they hadnt seen him. i asked him who he was with when he came home and he said them whicj obv i knew was a lie. i got it out of him that she had got the bus down and they were in an abandoned factroy for 2 hours. i was so cross with him and confiscated his phone, ipod and xbox and grounded him. i read his phone and there are messages saying that she hates me and his sister (who he is very close to) and he is just going along with this. she is trying to turn him against us. i dont know what to do now. should i let him still speak to her knowing that these things are being said and hope they break up evenually or should i keep him in and confiscate his things for ages? i am at my wits end with him. any help is much appreciated.
