Family issue

So my mil has come to visit and my husband originally told me she would stay few weeks but it's up to her. I don't have a problem with this however we live in a 1 bdrm 1 bath apt. My husband sleeps on couch and I sleep on a mattress on floor while his mom's got our king size bed! It's fine if it's a few weeks but twice now I have overheard his Skype calls to his sister back home and she says the mom will stay 6 months here 6 there. I wasn't informed about this! It's fine If we had space but we don't and to top it off fir the 3 yrs I've lived with hubby I've been asking for a family. He tries but not enough. It's like trying for a miracle. I am feeling the pain and neglect and I don't know what to do. I'm waiting for another Skype call and I overhear 6 months again and confront him. I feel like I'm going to lose it also because neither him nor his mom really help around the house and he recently got laid off so I'm the one working my ass off and coming home to serve them. I love my husband but I know if I say anything about his mom all hell will break loose. I have also been telling his mom about our issues as my last hope but deep down its useless as she doesn't speak up to him. She's afraid to upset him
