Unfortunately in my experience friends like that are narcissists and even if you very calmly and directly address the issue they will get defensive , not acknowledge their behavior or even turn it around on you and make you feel it's your fault. My best friend in middle school was this way. Everything was a competition, my opinion was invalid, and she was constantly trying to 1 up me.(which was also ridiculous cause I was pretty poor). Anyways. You recognize it is toxic...set some serious distance and see if she comes around or stays the same. There are plenty of kind, like-minded people in the world who will not treat you like garbage.
