I came across his phone, I didn't read the texts but so far today they've exchanged 40 texts. She contacted me via FB telling me she'd been seeing my partner until she found out about me, she humiliated me by copying my friends & family in the message. She said things about me that my partner only knew. He denied the affair but 2 weeks on, he's talking to her again & he claims they're just friends but they text all day
