I have recently entered my first LTR (together for about 2 weeks now) after learning about the redpill (I'm 25yo). So far I believe that I have a pretty good grip on the relationship. We only see each other on weekends most of the time, because of work and other shit I have to do and I like it this way.

Yesterday my LTR texted me, that she told one of her "friends" that we are officially together now (had sex regularly for about 2 months before she asked about being exclusive), and said friend told her that she would like to get to know me. My LTR answered we could do that if I was ok with it.

My question is: How should I go about setting this meeting up so its not boring for me and how should I behave around her friend the redpill way so she doesn't badmouth me later. This girl is single and sleeps around a lot according to what my girlfriend told me about her. My impression is that my girl would like to show me off to her. Even if I don't meet up this time, sometime in the future I am going to have to meet one of her friends so any advice is appreciated.

Edit: I misphrased this a little, the meeting is going to be me, my LTR and her. She just wants to get to know me. Sorry for the possibility for misinterpretation, english is not my native language.
