DD almost 18, has been with her 20 yo boyfriend, for about 6 months, at the beginning they were together a lot, every weekend and once during the week, she was so happy to be in a relationship. It has now tapered off to one evening at the weekend and maybe an afternoon.
I have been overhearing her trying to arrange to meet up with him. Last week when he was leaving our house, I overheard her asking, ' so will I see you on x day', his reply was 'maybe you will, maybe you won't' (they didn't meet up). This week they were together on Friday, I overheard her asking him if they could meet for lunch on Monday and he just said a very blunt 'No'. He stays overnight when he comes, ostensibly in the guest bedroom.
She appears to be very clingy with him, as she doesn't have any friends she can go out with after a falling out in her group of friends, so I can see that she feels she needs him to have any kind of social life and she is /was loving the idea of having a boyfriend.
Should I intervene and talk to her about what I see ? I have been dropping subtle hints, but DH says I need to stay out of it, but I hate to think that she might think this is how relationships are, where she is happy to have any scraps of attention and has to plead to meet up.
We are not in the UK, so are not breaking any Covid rules by him staying over, or them meeting up outside the house.
