They say talk about your values(dating)- but my values are not consistent- they change and bend at my lover's whims

- At my core i want to do good - i want to treat people well- i want what's best for everyone and am happier for it- but when i fall for someone my "values" become underlined and even "turn off" if my partner begins to show signs of an opposite inclination- not in my partaking of bad behaviour but in my " ALMOST" passive acceptance. Even if the person i fall for showed me a "princess" in her and turned out to be more of a wolf- i know her so well and i had already chosen her that i accept the torment she wreaks with little pushback- maybe i have no spine - maybe my values are just some fairy tale i enjoy "believing in" ... regardless i would not let go regardless of what someone does to me and i don't know what that says about me and how to even "fix it"
