So last year in december a girl i know recommend me for my future Job. My gf has a history to get mad everytime anyone whos not male messages me for any reason (study w/e). ive not cheated, we are close to one year relationship and i am annoyed by the fact she gets mad so easy for no reason. So i decided not to tell her directly. When she asked me how i know my future boss and how i got in contact with him i told her. she got mad at me for not telling her "because i dont talk with her about the important things".

No history with the other Girl beside casual friendship.

Im not a native speaker sorry.
