So I have tonight found condoms in my 17 year old DD bedroom. She has been seeing a 18 year old boy for 6 months. I told her i had found them and she told me she was having sex with him, although refuses to tell me how long they had been sleeping together for. I then went on to talk to her about possibly going on he pill and said I would go with her if she wanted me to. So i thought i had handled it fairly well. We do have quite a good relationship as although I would rather she wasn’t sleeping with him she has obviously decided she wants to and she is legally allowed to. I also want her to be safe and be able to come to me if she has a problem. BUT it all went wrong when I realised that they must have slept together when we were all in the house During the day as it has been during lockdown and there has been no time when they have been left alone. At this point I got quite cross and told her it was not respectful especially that at any point her Younger sister, father or me could have walked in at any point I said it was disrespectful of her boyfriend as well and I doubt he would do that at his house, she didn’t reply to that so I assume that is the case. It has now ended in a big argument. In the heat of the argument I said I also felt that he didn’t treat her well. They have been ‘talking” 6 months, are obviously sleeping together and yet he still hasn’t asked her to be his girlfriend. He has only ever asked her to his house once - he only ever wants to come here and even then my daughter has got upset because he never wants to see her more than a few hours once a week. They also went to the pub for the first time since lockdown finished last week and he completely ignored her. Even some of her male friends said he didn’t treat her well and she should talk to him about it. I have tried to keep quiet That I think he isn’t been particularly nice as felt it was her decision but tonight I couldn’t help myself. Now she is really cross with me! Told me to stay out of her relationships which is fair enough - although hopefully she will realise he isn’t been particularly nice. But i have said again I feel she is being disrespectful by sleeping with him when we are all up and about in the house during the day And i dont want it to happen again.( he doesnt stay over - she has never asked if he can). I dont think this is being unreasonable and i am now thinking I should tell her her door has to remain open while he is here. Am i being unreasonable????
