A wide mix of MIL and DIL relationships here. My MIL was a nice enough person but she simply did not want her only son to leave home, and any woman he had married would not have been good enough. This was not a surprise to me as my mother was exactly the same about me. DH was still living at home when we met because his mother had 'contrived ' to keep him there - but that's another story.
My MIL and I got along OK in a polite, distant sort of way (a bit like treading on eggshells), we never argued or exchanged sharp words, but I always felt like a visitor in her home never one of the family. MIL, FIL and my Mum all got along like a house on fire and became good friends, and my Mum was always included and invited to any family events eg Sunday lunch, birthdays and Christmas - and if she declined they took it as a personal affront!
When we announced our engagement my future FIL said I was not as pretty or 'well connected' as DH previous girlfriend, but he supposed I would do! He also said that he'd give our marriage 3 years and by then I would probably have left as he doubted I'd put up with DH long working hours. This year we celebrate our 40th anniversary - so he got that very wrong! He was always outspoken and the only right way was his way.
MIL and FIL both made a big fuss of our DSs when they were babies, but rather lost interest when they became talkative children who would ask questions or make comments on things. They never ever offered to babysit.
Our children were always polite and respectful to them but did not like visiting them as FIL was very strict about no food being left on their plates, no running around even in the garden, and they had to remain in one room where he could see them! Sunday lunch at their house became a bit of an ordeal.
In the early days of our marriage, whenever they came to our home for a meal my FIL would go into the kitchen and run a finger over the cooker top and the cupboards to see if my kitchen was clean enough for him to eat the food I had prepared! MIL caught him and told him off. I was not aware this happened but MIL told my Mum and she told me.
A few years after my FIL died we became aware that my MIL was struggling to live in their large house on her own. It needed a lot of repair and she didn't have the means to do it, and by then she also had mobility problems. We encouraged her to buy a smaller, more manageable, place nearer to us so that we could more easily help her. From that time our relationship deteriorated further. She became suspicious of me and even DH, so I stayed right out of any financial discussions and allowed DH to deal with it. It was a very distressing time for him as they had always been very close and he was only trying to do his best for her. She did eventually move nearer to us and we visited every day to take her meals (she refused to cook) and keep an eye on her. Later we arranged daily carers and any equipment or aids she needed. She remained aloof and frosty with me to the end, but on one occasion she remarked that our children had never really liked her. I denied this, but she said she couldn't love them because everyone she loved had left her. I felt so sad for her. When I did some Family History research after she died it revealed family secrets which might account for her remarks. She was always very secretive about her family and her past.
I wish I had been able to get closer to her and perhaps help her fully enjoy her grandchildren. I don't think I was a difficult DIL but perhaps I could have tried a little harder.
I vowed then to welcome my DSs partners with open arms and an open mind and never to interfere or criticise. I hope I am doing that as they are all lovely young women, and I think of them as the 'daughters' we didn't have. Time will tell - and I may never know - what they think of me.....
