Just venting.

I don't know what to do anymore, I'm 5 months pregnant and I'm so stressed out all the time because i feel like I'm locked in a house all the time with people that don't know how to stick with what they say, i cant talk to anyone here because its my in-laws that live with us and his grandfather, they all smoke weed and my fiancè grandfather does other drugs that i dont want my kid around when he/she is born but my fiance doesn't care because to him family is more important and he has some kind of disease, he likes to piss on the floor in the bathroom and doesnt clean it up or anything he is a nasty, perverted old man, i cant even walk around in my house in a comfy shirt without a bra because i get stared at and im so done with it i bend over backwards for people and after so many chances im done but no one cares what i think, my fiance wants to get a new place because are renting from this person that causes problems but he wants everyone to go im fine with his parents but his grandfather im not but to my fiance he dont care. Im so fed up i feel like giving up.......
