Should I be worried that my girlfriend goes to other guys for help?

Whenever my girlfriend gets in a mood or something bad happens she goes to her other guy friends for help.

Just recently she said something bad happened and she didn't want to talk about it and she said she's sorry if she seems like a bitch.

Then i went to instagram to see if she and her friend are active and they were showung that she was talking to him and they were active for 20 mins. So i know that she told him shit and won't tell me.

This happens quite frequently and it bothers me that other guys know important stuff happpening to my girlfriend that i dont even kniw about. Am i overthinking this or not?
