Hi there! This is my first time posting here and I'm hoping to get some perspective on a current situation I am in and maybe some solutions too.

I currently live with three other roommates, two of which; have BPD. in our household everyone is very supportive of each other's struggles and for the most part we stay transparent with where we're are at on a day to day basis. 

Two of my roommates are primary partners and then it's me and my other roommate (let's call them Peter). Peter is one of the two that has BPD and then one of the partners (let's call them (Karlee) also is diagnosed BPD. As of recently, Peter and Karlee have grown especially close to the point of where Karlees partner and myself almost feel left out of the whole friend dynamic. Karlee and Peter are ALWAYS together. I've also noticed that as they have grown closer both of them have basically stopped communicating with me or the other partner in the relationship which is a red flag to me. 

My best friend also has BPD and her and I have talked about that extensively and I am aware that I am her FP.... I almost wonder if Karlee and Peter have ended up being each other's FP or just one of them possibly? I'm not sure. I do know that Karlees partner has grown increasingly frustrated with what's been going on and they feel like they are loosing Karlee to another partner. I guess maybe I'm just looking for some insight as to whether Karlee could be Peters FP or vice versa and how to bring that about in a productive conversation. And if that is not the case how to bring about a conversation in general without Karlee or Peter feeling ganged up on or cornered. 

Thanks 😊
