How do I navigate this ?

r/

I don’t have many people to talk to I’m trying to get in therapy but easier said then done, my girlfriend is best friends with the only person to make her cum with out toys like ever apparently, I wouldn’t stay associated with a person that I had hooked up when in a relationship with no matter the circumstances. She also tells me about having so much “ meaning less sex “ and not even able to know her body count. This is really off putting and kinda a turn off. this person that she considers her best friends invites us to things party’s and what not and just don’t want to participate i wouldn’t ask her to cut her out of her life. It’s a small town and she’s her “best friend” I don’t understand how it’s not a big deal she thinks I’m boiling the relationship with her friend to that one time that one bender. But I feel disrespected, like I said it’s a major turn off. I just don’t want to associate (just my person)
But she’s saying she doesn’t know how the relationship will end up working. We really care about each other I have been thinking I have to let her go, this is something she’s not really willing to meet me half way on, I don’t know what to do / think honestly I don’t want that person in my life Ik I cant ask her to cut her friend out of her life, it’s just every time we see her it’s mentioned, I don’t want to be the good guy she’s finally found after being a big big hoe. I don’t think is she’s willing comprise or anything she just wants me to associate with those type of people she’s still calls friends and just thinks it’s not a big deal.
