ladies, how do I convince my SO to have us get into our own place? we went from living with his parents, "sister" who is never there, and nephew to my friends "guest house" that has no bathroom it's just an open room really where we have to walk into their home to use the bathroom and kitchen... how to I convince him that I'm not comfortable with our situation even after I have bluntly told him I don't wana be here I want our own space with our daughter
