I'll try to keep this brief, joined hoping for some advice. My Dsis found evidence this morning that her OH has been having what looks like an EA with a work colleague for the past 5 months. Hundreds of messages, some explicit/ include graphic photos and additional references to cybersex over Skype etc. They've met up but it's clear from the message content they haven't done anything physical, yet. There were other references to him having anon online sex with others previously.
For context they've been married 7 years, together for 10, 3 dcs (youngest 18 months). They get on well and she is particularly devastated as she didn't see any classic signs- no hostility or additional secrecy etc. She can't get her head round splitting up but also accepts that this IS an affair.
How can I help her? I'm so gutted for her and feel absolute rage towards bil don't want her to make compromises in the shock of the moment. She plans to confront him tonight. Any wisdom welcome- re: what to say/ do to support or resources for her to help her understand options re: counselling or separation?
