Been with DP for a long time.
We have always had issues surrounding what I feel is his over protectiveness towards the kids and him leaving me to the donkey work of parenting and him being the "nice" parent.
Our girls are aged 19, 17 and 12. He refuses to spend time alone with me if the children are home, he won't even sit in another room with a glass of wine or have an early night with me. He will take me out to dinner if the kids are out with friends or with the grandparents but that doesn't happen very often. If our friends arrange a night out, he will go but then he tries to get the girls to go out so he doesn't feel guilty!
He has a difficult relationship with his own Dad and despite still working with him every day he can't really talk with his Dad and I wonder if he is trying to compensate? Ironically, I feel I have a better relationship with the girls than he does because I really talk to them rather than just sitting in the front room while they are all glued to their various devices! 
I've talked to the girls and although they are teens and happy to have someone to run around after them, they have all told me that they think it's a bit strange he won't expect them to change their plans so we can do something ourselves. In the summer he literally refused to come to a friends BBQ because he didn't want our eldest to walk home less than a mile away from the bus stop on a beautiful sunny afternoon! 
When I try and talk to him he just says he wants the best for our kids and I should too. I point out that it is me that reminds them to do their chores and it is me that helps them with school work, chats about their day, cooks and cleans etc. He just wants to be taxi and have them by his side all the time.
I love my girls dearly but I don't feel it's healthy for them to never be allowed to stand on their own two feet and have to compromise. He works from home so picks them up from school and work everyday rather than have them walk home. My DD2 has knee problems and has been told by physio 3 times that she needs to exercise it regularly but he still insists on driving her everywhere and tells me to stop nagging her. :-(
When I'm down, I just feel that he sees me as the housekeeper and don't really have a say in my own home or in my relationship as a partner and as a mother.
