15 yo Ds seems to have started first relationship although says 'she's not my girlfriend'. Invited her round twice (she is also 15) but she would barely look at any of the family, despite effort to make her feel welcome(l appreciate this can be daunting). Dd of 11 said 'she won't even acknowledge my existence'. He only seems to have known her for a couple of weeks and has now asked why we have said she isn't allowed in his room with the door shut. Together they seem awkward and communication is stilted. Two mutual friends seem to have paired them up. He suggested that rather than going to the cinema with her and other family that the family go and leave them at home! I am concerned that (reading between the lines) there isn't enough there to support this relationship 'going upstairs'! Ds is resentful and has just said 'l can go in her bedroom' !. I want to support emotionally healthy relationships for both of them but all they seem to want to do is sit in a dark room 'watching tv'. Feels awkward. Advice please, first teenager! Thanks.
