I feel like this is bullshit. Sorry, but I don’t experience anything like this with my partner.
Maybe some people do project their traumas onto their partners- I feel like my mother did for example. But I don’t see my partner as someone who hurt me or anyone similar to anyone who hurt me. Nor does he see me as anyone who hurt him. We have a very healthy relationship. And the ease of our friendship, the intimacy we have in being vulnerable together — THAT is what leads to our physical chemistry.
