Hi I’ve been here, not with a boyfriend but with friends. My eldest is nearing on 18 now and she (much like I did when I was younger) has a tendency to become involved with some dodgy characters. she’s learning, like we all are and she has cut friends off in the past when she realises which I am so so proud of her for as I know myself how hard that is to do. When she was knee deep and totally blind to the toxic relationships she was in the only thing I could do was be patient, be her friend, support her and make sure she was staying safe. With teenage girls especially I find the more you force your disapproval and try and control them the more they often pull away from you, they can be fiercely rebellious. it’s a tough time! when your together with your daughter maybe try and keep the topic off her boyfriend and chat about other things to lighten the mood, try not to tell her what you think she should do but give her space to express herself and she might open up if She doesn’t feel like she’s being judged. From her point of view in her mind you are trying to control her too by telling her he is no good for her. Maybe invite him round for dinner or something, you know what they say .. keep your friends close..
