My 16.5 year old daughter has her first proper boyfriend, he’s 17. They have been together just short of 3 months. he lives out of town and they don’t spend much time together. However, during the school holidays, he visits his nan who lives not far from us. During one of his visits to our area, I invited him over for dinner ( just to get to know him a bit) and they sat down downstairs watching a movie. All went fine until he left the house and a message popped on my dd phone , which admittedly, I glanced at it. He was saying how much he enjoyed “ a the things they did” and how brave she was. I was mortified by it. I didn’t open the message so I have no idea what he meant by it. The point is I was at the house with them, literally in the kitchen and they were in the front room with the door open! I just think it is just a total lack of respect from both of them. DD has autistic traits and still very much young , despite being 16. I wonder if by calling her “ brave” he’s somehow manipulating her?
I’m just looking for some guidance, advice on how to approach the subject with her.
