Earlier tonight I caught my Gf lying to me about something stupid. A chore needed done and it was her turn to do it, I asked her to do it and she said she already did it today. I knew she hadn't done it, but she assured me when i went for a nap earlier she did it. I told her she was lying and she said she would swear on her life she did it. Then I noticed a bit of evidence that proved she was lying. Something so silly and insignificant has now got me feeling horrible emotions of mistrust and anger. I yelled at her, used strong language etc I don't even know if i'm overreacting or not ,it's so insignificant ,yet at the end of the day she has broken my trust to some degree .. am i overreacting about it or was i right to yell?.. would you feel the same way? this is the worst thing to happen so far in 5 years of being together.
