I have two siblings, both divorced, both with children of their own, the dads aren't really in the picture and it seems to have fallen upon my shoulders to fill in this gap. I have become the support for both, i have given them over a year of constant babysitting and constantly staying over the weekends. My husband hardly sees me and when he does it's because I'm having the children overnight in our home. They trash my house everytime and do not help tidy it up and help themselves to all our food. But if i say no I'm told I'm lazy because I dont work, i dont do anything (this is because I dont drive and can't take all seven of their children on a bus alone) and I'm being selfish because they never get a break.
I've tried making it so certain days every month I will have them so i can have time with my own family but this doesn't work, they initially said this was a great idea but they still just turn up whenever they want, to the point where I lock my door and pretend I'm not home. It's effecting my marriage, my children and well me, I'm always tired from the constant child minding, i do not get money to watch them the majority of the time. I'm so stressed out, I will have 3 days this entire half term with my husband and daughters, the rest is babysitting. But saying no nicely just isn't working and if I just outright refuse it ends up with me getting constant grief from everyone. I dont know what to do anymore.
Should I keep babysitting or deal with a huge family argument?
