So I posted on here a few months ago about my husband texting a girl from his old job. Well he quit talking to her that night when I caught him and I've been checking our phone bill (secretly) to make sure. Well now her number has showed up on incoming message a few times but there are no outgoing messages. So this bitch is still texting him but he isn't saying anything back. Should I ask him about it or should I just confront her myself?
