My (21M) gf's (22F) best friend (F21) keeps suggesting to join us in bed, how do I approach this? (Update)

The rules says one update is fine so here I go. Excuse my writing, this was a lot to unpack https://www.reddit.com/r/relationship\_advice/s/lFuMNaND13 original post I did have a good long talk with her now and I was pretty surprised by what she told me. Apparently when they went to that theater show, at some point the friend asked about her and my sex life now that we're living together. My gf admitted that she did "brag" about me a little bit and that got her friend's attention as well as had her admit that she'd love a threesome. The reasons she gave were apparently that 1. I'd probably love it because why wouldn't I. 2. She, meaning the friend, hadn't had good intercourse in a long time and 3. That since they're so close friends, it wouldn't be a big deal/nothing best friends wouldn't be able to deal with. So that's what happened in the theatre. She then went on to tell me that she was uncomfortable with the idea but due to their long friendship she didn't want to outright tell her friend off. I now know that her friend apparently is a pretty horrible person when it comes to getting what she wants and leveraged the fact that she was always there for my gf and apparently saved her life at some point as well. When my gf first told her that my initial reaction was one of confusion and disinterest, her friend began to do just that, it would be something she owes her etc. So emotional blackmail at that point, I'd say. After that her friend told her to let her talk me into it/leave it to her to convince me, which led to the speaker mode calls and my gf telling me about their "conversations" whenever they met. My girlfriend confessed to me now that she felt like going against her friend's suggestions meant losing her oldest friend and that she was just very torn emotionally about having to make such a huge change, her thought process was that our relationship was going to survive a threesome and her friend would just stop talking about it after and everything would move on as normal. I'm not going to sugar-coat it, I straight up told my gf that her friend is emotionally abusive and manipulative, that whatever good she did in the past should be appreciated but not taken as a free pass to have my gf allow her friend to do whatever she wants without much resistance. I was right here with her and that I can and will be supporting her no matter what happens but she needs to tell that friend that she's overstepping and if she doesn't stop, she needs to cut contact with her friend. As you can imagine, it was a very emotional talk and my gf was crying a lot, which is really rare. We sat together for a while after that but eventually my gf took the leap and she and I together have confronted her by now. The conversation was pretty heated and half of it would probably break guidelines but the gist of it is that when my gf told her friend about our sex life that amplified an already existing attraction that friend had towards me, the part about her friend not having had good sex in a long time apparently wasn't a lie either. She tried to defend her actions at first but when we told her that this had to stop, she exploded on us with a tirade of insults, emotional blackmail towards my gf and almost a physical altercation between her and my gf had I not kept her at a distance. Needless to say she's now blocked on all of our social media and contacts although we decided to leave it at that, hoping that would be the end of it. Thank you for all the advice you've given me in the original post, I feel like my relationship with my gf is now even stronger since she took this big step for us both. Tldr: My gf's best friend was jealous and couldn't take no for an answer, she's now gone from our lives, hopefully at least and we go out of the situation with an even stronger bond submitted by /u/Okita_Souji03 to r/relationship_advice [link] [comments]
