I see a lot of posts where the guys are surprised their wife wants to leave or they miss her.

The hard truth is that she's leaving cos she's banging someone else. You can deny it "No, not my stbx", but it's true.

As for missing her, while you are being sad and crying, she is letting some guy hit it like she never let you hit it. Just think, as you are looking at old photos, she's riding a guy all night whom she just met and who she'll never see again just cos "she wants to experience things".

The best revenge is to live well. Go to gym, fix your diet, get some confidence and hop on Hinge and Bumble. The best way to forget her is to find someone else (but never marry again)
