My girlfriend lies too much. She tells her friends stuff that is not true and when I confront her about she lies and says she didn't say anything or do anything...
Trust is very important for any relationship. But she keeps lying to you. You need to decide seriously about this. Coz by going this you can't go the long way.
Make a distance then try to not talk to her for days, weeks or even months. If she comes back to you then she is yours forever . But if not, she was never meant to be your girl so you have to let her go
