ok so lets say for example you Legend my dear are in a long term realtionship with a girl-- seeing each other for 5 years, ultra committed and serious, engaged and living together.

One of your pals says ' Oi leg-- i saw your missus today in town with another guy'

So late that night you ask her outright --

she admits it and says she was killing some time and this guy came chatting to her so they both went shopping tryong on clothes.

How would you feel?
