Is NOBODY wrong in the post ? POST : Hi reddit,

So my girlfriend of 5 years has admitted to me tonight that she had feelings for about 2 weeks about a guy she frequently plays Call of Duty with. She told me she’s comfortable talking to him about her life problems etc and she suddenly realised how she felt and has been absolutely guilt ridden since. Couldn’t sleep for days etc.

I told her its hurt me deeply knowing after 5 years she could think about someone else like that

Am I the asshole here? I’m just not sure what I should do, I don’t know if this means her feelings arent strong for me despite her saying so and its a pretty unique situation since its through online rather than a coworker etc. She plays cod a lot with a group of guys for hours on end so its not like she barely knows him.
