Wife of 10 years broke up with me a couple of months ago giving a few reasons: I love you but I'm not in love with you, I want to be alone for a while but in the future experience a relationship with another man. We're still living together for financial reasons and most of the time sharing the same bed. We have a daughter that we're planning on telling in a week or so.

A few weeks after she broke it off, I found out she'd been sexting with another man. I confronted her, we argued briefly, then she become regretful and said she had been naive and that it would stop. I knew it wouldn't.

Fast forward to the last few weeks, she's obviously still been messaging/sexting another man/men. The smiles as she reads the messages - she rarely smiles like that. She rushes off with her phone and locks herself in the bathroom. Stays up late at night and won't put her phone down even during the night, often waking up at all hours constantly checking the phone.

She fell asleep the other night, phone in hand, unlocked and with a chat on screen - including a photo that she'd sent.

Do I confront her again and risk the mother of all arguments or for the sake of the "family" and an amicable split/divorce keep it to myself?
