I don't feel a need to have a conversation about it. I am at peace with it. And I don't think this is really going to affect them like that. It'll be onto the next one.
I mentioned before that she ignores my attempts to talk about anything serious or really anything not about sex and that's another reason I'm just letting it go. It makes me feel silly and insignificant.
I guess I also feel like since they have each other and their primary, most important relationship is still intact, they will be fine and it won't be a loss. I am the loner here.
