My girlfriend 's sister is always really mean to me in front of my GF . My GF defends her when I stand up to her . My GF says that she is her sister and she will defend her sister and I should just learn to tolerate her sister . Should I break up with her ?
When my girlfriend 's sister is mean to me and I defend myself , my GF defends her . When her sister is mean to me and I ignore her , my girlfriend gets angry with me for ignoring her sister . What should I do ?
