I lived with two women once….my girlfriend and her best friend. Only problem there was her bf had developed an unhealthy co-dependency with my girlfriend, and she was trying to break out and start her own life. So there were some jealousy issues…but this friend was very emotionally stunted…I think it was way harder on her than on either of us. Bottom line, depends on the people…I think any time you live with any other people, even just one person, if your personalities don’t mesh, it can be problematic. But hey, life is short, do what works for you now, and if it stops working for you, do something else.
