Vent all you need to. I believe it's an important part of the grieving process. I had some parts abuse, yet, there was also a lack of feeling connected, there was much more than just sticking that label on it. Not even close to being on the same page, probably just different books, altogether. My heart broke many times over. I was in my mid 20's when I met him. He was in his mid 30's. I believed in the notion of talking things over, not letting the sunset on anger, being friends was important. And I mean yes, those things do matter. Yet, I believe there was a ton of yes dears to me, whatever you say. However, that does not an authentic relationship make.
Sending you moral support as you go through this.
