Someone shoot me

I cant stand all this $hit!!!! With DH now living in my mother' and my apartment it is H ELL!!!! My mother cant move out til my sister finds a nursing job and she will move in with her, they need a bigger place. Plus DH is out of work and my mother and I are paying for eveything here.
So DH hooked 'his' TV up in the livingroom. Now my mother always domained the livingroom and 'her' TV til DH moved in. Now it's a battle!!! DH is home most of the day and can watch TV play video games and whatever but, he doesnt stop when my mom gets home. He says its 'his' TV, bla bla bla. He does give the TV up at times, dont get me wrong but, I have my mother stopping around, slamming doors and him thinking he can do whatever he wants.
Am I making sense right now
I cant stand that they cant share and they are grown people.
I look at it like my mother pays here share to live here she should get the TV when she gets home from work but, she should share it as well. Also she has to stop acting like a baby and use her words, my mom has always been that way. Just like DH needs to learn that it has been my mom's and my place for 8 years, we are paying the bills and we dont need 'his' TV hooked up, my mom's was fine and when she moves out 'his' TV can get hooked up. Then we dont have to hear that it is 'his' TV.

UUUGGGGG Im just stressed and fighting with the both of them. DH has moved in here thinking he can do whatever he wants but, doesnt realize he cant. He moved in here with us, my mom, son and I and things are alittle different then just the 2 of us living together. This is putting a HUGE strain on all of us and I jsut dont know what to do anymore.

Sorry just needed to vent
I just wish they would comprimise somehow
