What do i do when i feel so smothered?

My husband and I moved in with my husbands grandparents to care for them. His grandfather has since passed, leaving us with his grandmother. Then, recently his mother moved in as well, so our home is a bit crowded, but the mortgage is so high, we all have to stay to cover it.
The biggest problem for me is that for the first time in my adult life, I have absolutely no control over my surroundings. It's absolutely driving me over the deep end. Now everything that's mine has been either relegated to the windowless basement/office, the garage or our cramped bedroom. And even then, my mother in law drives me nuts with trying to re-arrange my space constantly. "wonder if you move this here, or that there, or if you get rid of this or that..." I'm going crazy!
It was hard enough trying to merge with his manic-depressive grandmother, then have his busy body mother here as well... I want to run away, but I love my husband so much I can't leave. Is it too much to ask for a space to ourselves? It's not like we can cuddle on the sofa with his mom and grandmother there!
Anybody else out there going through the same thing? Words of comfort? Want to form an overcrowded house support group?

I'd definitely be in the same boat if I were you! I am sorry you have to experience this; yes I have definitely been there so let me give you some good words of advice. I think it will in the long run hurt your marriage with your husband because you're not getting that quality time to communicate or just to spend together. It definitely is not a bad thing to ask for space - I think his mother and grandmother would be able to get their own place and it doesn't have to be far, it can be somewhere close but enough distance to where you can breath and feel more of yourself. I can tell that you're definitely getting tired of the way things are so maybe discuss it with your husband first because he needs to know your heart and what is on your mind - you owe him that and it'll strengthen your relationship! Good luck, take care!

i feel for you, i don't really know how u feel cause i never been down that road. all i can say is that your not asking for to much all you want is your space and your husband should really understand that. every female want there own space, we don't want our things in no garage or basement. i think you just need a break, a nice little get away. hope everything will be fine.
