Namechanged as my children know my other user name.
I was looking at my husband's phone last night (he knows I know the passcode and I was looking for updates to a WhatsApp group we're both on). I found messages between him and a female colleague, full of pet names for each other and making it obvious that they're very close. There were messages from only the last day or so, but the chat before that had obviously been deleted.
I asked him what was going on, he promised that the chat was as far as it got, nothing physical and I do believe him. He also promised to stop and said that I could check his phone anytime.
I feel so devastated though. We've been married eighteen years and I love him. How do I move on? From anyone who's been in the same situation, would talking to the colleague help? I just don't understand what was going through their minds, especially as she's apparently happily married too.
