Hi, My dh and I went away for a few days recently. My daughter has just told me that she discovered our son in bed with his girlfriend (she had climbed in thru bedroom window). As far as we know (which is not much as our son is non-communicative) they have been dating for about 4 months. He is not a child, he is 18, but we are deeply disappointed and hurt since he knows how we would feel about this breaking of trust. (He has been a problem teenager for many years, drugs, dropping out of school). How should we handle this situation? Our daughter told him that she wd not tell us, so we don't want him to know that she went behind his back to us. Our youngest son (we have 3 altogether) is 16 and also naturally interested in girls so we do not want to send the wrong message to him either.
