I found out recently that my partner last year messaged a girl that he met when taking his car in to service.
He added her on Instagram and messaged her - from what I understand there were a few messages. He said the messages weren't bad and that he was just thanking her for the service - she's not un-attractive which I'm sure helped.
This isn't the first time I've heard things but he says it's all just normal conversations with them- he says he's a social person.
We were together 7 years and I feel betrayed and embarrassed.
Am I overreacting or is this unacceptable?
