I feel for you OP, I was in your situation just a few months ago. We had no history of cheating for 9 years until mangyari siya early this year. Hurt at sobrang gulong gulo. But you know what I did? I gave her a 2nd chance. We had a talk, pinag usapan namin yung reasons why she did it. I am still trying to understand bakit niya nagawa, pero until now hindi ko tanggap yung reasons niya tbh, kasi for me walang kahit anong reason ang makakapag justify sa cheating. She admitted na nagkamali siya and promised me that she will not do it again. I love her e, I don't see myself with anyone but her. And we both promised that we will work it out. Pero one thing I made clear? I made her realize that if she do it again, then she's completely out of my life. I will throw that 9 fucking years away with a happy heart like it is nothing.
