Traits you don't like about your partner that you put up with?

She was always jealous of her sister-in-law. It drove me nuts because I saw this amazing person, but she couldn't see it in herself unless she beat this one person. I ignored it for years, but honestly it was emotionally exhausting. I was stupid enough to think if I heard her out she would stay, but it was just an excuse to let her walk all over me and when she left it broke.me.
Lesson learned: call peolle out on their bullshit, no matter how much you love them.
