My gf regularly meets another guy in our local town. They go for coffee. Or sometimes to the pub.
Other guy is someone we both know. And they tell me, its just friendship and company. (I work long hours, and they both have a lot of time on their hands)
To me, it feels like a betrayal even if it is purely platonic.
Their meets are very regular. They spend a lot of time texting each other. I'm not the type to snoop on her phone. But did have a look one time, and she'd deleted all messages.
Should I be concerned. What would you do?
