OP I think you don't question his hobbies as there's a part of you that feels there 'may' be more than hobbies. I feel that you look at life and think what if I were to lose it all, but seriously wouldn't you be just as happy living in a modest house with maintenance for your DC & yourself, than living in London, on a street where it's likely countless women put up with the same, in the name of a lifestyle.
If you were to look at your life you would like a DH that goes darling you're marvellous, everything is sorted. Thank you. I'm going by bike today so I'll grab a few things for my bag, I'm sorry I should have said. Then before he goes to work he kisses you and says goodbye to the DC's.
You want a DH who gets home from work after you've sorted tea, that says ooh that smells delicious, have you had a good day? Going to put my mobile on silent for some family time. Is there anything you want me to do?
OK that's a bit dreamy, but I bet whilst you were unwell Saturday you could have cursed the daft bike ride and all the time he gives to his hobbies.
I think I recall a similar thread from months back involving similar.
By all means vent on here, we are only going to tell you what you already know. Unless you want someone to say it's fabulous you do so much, but really DH & the older DC should be sorting themselves out. It's not fair on you?
Would you feel like you had no purpose? Your purpose is being happy and showing your children how to exist. How great would it be for the older children to pack their bags, to ask you to double check? How great would it be for your children to go Mum, how do you iron could you show me please?
If your children don't do chores that should change from today too.
Honestly you can get planners and planning stuff from Wilkinson's or any other shop. Do something for you.
