I hope someone is going to be able to help me. My girlfriend of 4 years has been talking about being polygamous. Now all of a sudden there is this girl. We have been letting her live with us so she can get away to a safe place. It seems that things have gotten better for her now, but she is still living here. Now last night my gf and I talked about the polygamy thing. So this is now happening. It turns out they have kind of been in a relationship for a couple of days before this. How do I share her? How do I come to understand why she wants this? This girl is already saying that she loves my gf. I really need to understand this so it doesn't hurt so much. Also, I guess this girl is moving in with us.
