welcome!

Being on the opposite end of a situation like this i can offer some advice my friend.
Number one- If you want her back thats great, but it is HER choice. You cannot make the choice for her.
Number two- Be strong. I know its tough but dont let it get you down. Women are attracted to strong men.
Number three- I say let her blow off some steam for a while. She will need it. That is one thing that I HATED that my ex-wife did....she constantly called and texted me after i cornered her with the evidence.

Good luck my friend!
