i [37m] and my wife [35f] just opened our marriage and she's is already talking about leaving me. i feel absolutely betrayed. she brought up nonmonogamy a couple years and we had put the conversation on hold when we found out she was pregnant. over that time we talked about our marriage, our love, my insecurities, what all this would mean to us. she assured me over and over again she'll always come home to me, she only loves me, it's just sex for her, all she wants is a girlfriend because she's bi. then i find out the very first person she talked to was a guy and now they are talking about getting married, like what in the actual fuck just happened?! i read everything i could about what enm was about and what it can do for an already great relationship and mentally and emotionally prepared myself for opening our marriage only for this to happen. i feel like i was prepared and ready to open our marriage and she was just going with what sounded good to her. my wife also has adhd so part of me is wondering if this is just one of her hyperfixations, it's new and exciting and she's getting dopamine dump after dopamine dump or if i should see it for what it is and start protecting myself and our kids. i just don't know what to do as it's all too fresh right now.
