Sparkling none the wiser

[Sparkls]

Yeah I got a message from a mutual friend who was playing games with him and could hear OW in the background talking about his days off and blah blah.
And really, I'm just disgusted by the whole thing.
Today at least, it feels a lot like what I imagined feeling "done" would feel like.
Of course, my emotions change on a daily basis. But hearing about him being all happy with OW didn't send me into a tear fit. Instead, my reaction was "she can have him."
If he's going to cheat on me after 8 years when the majority of the relationship was "open." then the chances of him being faithful to anyone is basically none. And, and this is the petty part of me, she deserves to have him do that to her.
