My daughter was married to a lovely man or so we thought. She was vulnerable and suffering from depression and trying to extricate herself from an unsuitable relationship when she first met him and he was very protective and caring. Their relationship developed quickly and within 2 years they were married.
Cutting a long story short, over the next 8 years he became more controlling. He would dominate family conversations, cut short visits even when arrangements were made for them to stay several days, they would stay only a few hours. I was like Pat Archer, just seeing the charming side and just grateful that my daughter was being looked after and I tended to ignore the odd strange behaviour.
Alarm bells started to ring when my new daughter in law met him for the first time. She had experience in the past of living with a controlling partner so could see the signs. After my daughter and her husband had gone home my son told me that his wife felt that my daughter was in abusive relationship. I laughed it off. Later other people commented to me in the same vein and I started to look at things with fresh eyes. They finally split up 2 years ago at her instigation and she has blossomed. She has opened up to us about his Jekyll and Hyde persona and the non violent controlling behaviour he exhibited. Interestingly when I first met his father I noticed that he manipulated social situations in much the same way as his son. I remember saying to my daughter early in her marriage that if the son turns out like the father, run like hell! So glad she did.
