I feel I need to preface this by saying DH and I were divorced well before we met, so not the OW or anything like that! Also, DD and I love all of his kids. Please don't flame me**
DH has four DC from his first marriage, ages 23-17. I have one DD from previous marriage, 8.
His youngest, DS is 17 (18 in April) but has always, understandably been the baby of his family. All fine. But, sometimes he can start what I consider to b inappropriate conversations in the presence of my DD, so, mildly sexual, or calling people fat, swearing etc. In DD's eyes he's a grown up, and I guess I'm uncomfortable with it. I think he's not used to having much younger kids around so probably doesn't know, if that makes sense?
WIBU to get DH to have a super gentle conversation with him about it before they all come to stay over Christmas?
