A friend... i think?

So I have a friend from high school I recently reconnected with. I haven’t had friends for a few years so I made sure to basically walk on eggshells this time to not mess anything up. Things were going great until I started my weight loss journey.

We were both about the same weight when I started. She was super supportive and excited for me to start this journey... until I actually lost some weight. By the time I lost 50 lbs in less than 5 months, she started getting distant. She wouldn’t comment on my pictures or updates anymore. She stopped talking to me as often. She would even post things on facebook/instagram/snapchat that were anti-diet/exercise or when we did talk, she would recommend podcasts or blogs about why you shouldnt show too much importance to physical appearance or take pictures of yourself and post to social media or how dieting is so bad for you or just stuff that was clearly against my journey.

Normally I wouldnt be bothered by this but I’ve started to consider her a close friend and seeing her being practically unsupportive and almost malicious towards my journey from what seems to stem from insecurity or whatever really bums me out. I took it personally. To the point of deleting social media, not taking as much pictures, feeling almost shameful of my journey (even though I have worked super hard and am really proud of my results). I try SO hard to not shame others (or come off as I am) for their lifestyle choices or become full of myself online because I’m so afraid of something like this happening and have those close to me hate me.

My husband thinks I’m crazy 😐 but I feel something is wrong. What should I do?

Should I talk to her about it or just let her deal with her own feelings & cut the friendship off slowly?
