My partner of 12 years and I tried to introduce a third into our relationship. Recently it got to a more serious point and our third decided that he needed to take a different path separate from us. We spent our last night together crying and cuddling on the couch in front of the fire. All things considered it ended really well even though it hurts for all of us a lot. The problem is that my partner is so hurt over it that now I feel terribly alone. I feel like he's blinded by his pain to the fact that I'm still here. He thinks I'm hurting because we lost our third, but what's hurting me the most is how alone his pain is causing me to feel and, although I've tried to tell him, he just doesn't understand it. Obviously I don't want to add to his hurting by flat out telling him that he's hurting me either. I just feel lost in all of this right now.
