Whilst I was away for work at the start of the month, my partner went out for a night with a few friends.
She told me she got a taxi home with her friend at around 03:00am but I have since seen a message she sent to that friend the next day saying “sorry I lost you and hope you had a good night”.
Obviously I was suspicious so I checked her Facebook. She used to get messages from a guy she was seeing before us and has never deleted the chat but didn’t reply. This chat is now deleted and their conversation is blank. She had feelings for this guy and used to regularly meet after a night out before we were together.
What should I do?
