Last night my girlfriend of 6 months and I had a talk about past partners after dinner. I should know to deflect this question by now but my past partner list while we were not exclusive only brought some passive aggression and bitchy jokes from her. "She looks like a bitch" or "I can tell she goes to *uppity college in city*." She initially told me when we were non-monogamous that she was only talking to me and can't stand that I won't date her. She ended up being the one that came and helped / hung out when I had reconstructive knee surgery and that showed quite a lot of value in her to me so I started dating her in May. Going through her list of people she was talking to while we were non-monogamous changed last night from 0 to 3, including her ex that she continuously stated "ruined her life." When she showed me their instagrams I thought nothing much of them, some fratty decent looking dudes. And then I see the latest post of her ex being a shirtless shot at the beach, pretty ripped, posted in late august. She had liked it, along with many previous posts, and was messaging him in late march when we were not exclusive but when questioned about the last time she spoke with him she stated summer 2016. My obvious caution was the messaging was very inviting for him to come down and visit her and stay with her. She claims that her messaging was all joking and she didn't mean but I can feel it in my gut if I stay in this relationship this will bite me in the ass. I am planning my way out already but would like to hear other RPers opinion on this matter as this is my first relationship under RP knowledge.
