I'm fat, uncomfortable, & in pain. My bed is no longer comfortable the only place I can get comfortable is on my sofa. But, I can't sleep on my sofa because that's where my father in law sleeps & has been for months now. Mind, you he has his OWN HOUSE 20mins away where he pays bills, with his wife; who sometimes comes here to spend nights with him. My fiance complains about him being here but has yet to say anything and its been going on forever, he'll go back to his wife for maybe a month or 2 then he's back here for almost a year. & on top of this bs the house we've been living in(paying monthly rent) for almost 4 years the owners sold 2years ago & just decided to tell us something & now we have 30 days to find somewhere else to live. Isn't that just fucking great.😒😒😒😒
