My gf of 3 months now is always telling me to go "try talk to other prettier girls" and telling me to "try to get the prettier girls if I have the chance".

She's been constantly saying this and she said like "If I was in your position and if I got a shot at a Korean Oppa, I would".

I am getting quite annoyed on this. I have tried telling her nicely that she's all I want and I do mean it but she said "Since there are better ones out there, I am at loss for not trying the better ones". And also she keeps mentioning that "I can just put her at the side and treat her like side chic cause she accepts the reality that nothing is eternal and that she isn't committing 100% on this relationship with me because she doesn't want to get hurt too much".

Yes, she had gone through an ex cheating on her but it was like many damn years ago. I feel very tired handling this.

Any suggestions?
