It's interesting how this thread has been dominated by discussion on the way in which soon dealt with conflict within her own family, somewhat diminishing the original OP.
flutterby123 - I do hope that some of the comments here have helped you. So many of us have dil or sil who don't fit our idealised image of our much loved adult child's life partner. I have read the thread as it's unfolded, but can't recall if anyone has mentioned the various threads on gransnet (and on mumsnet) about family breakdown as a result of parents/partners of adult children where conflict has resulted in long term exclusion of formerly loving family members from each others lives.
Mr i.am often comments he wouldn't have chosen either of our daughters partners, but he loves them nonetheless, because our daughters love them and so far, have been happy with them. For this, I am grateful.
