Need help getting started
I have been seeing a guy for the last year and a half and he has been in a 7 year relationship with another girl who has been living with him for the past 4 years. I know about her but she does not know about me. We want to involve her and introduce the idea of polyamory to her. What is the best way for us to introduce the idea to her since she is unaware of us and the whole idea?
