Why did this shake me?

When I met my now partner, he was in an on and off situationship.

The moment he met me, he completely broke it off with his ex and started courting me.

She went ballistic, blasted me on social media, called my mom and my church. Paid to have us followed. I got a restraining order, and still, she tried to physically attack me. Thanks to her, I developed anxiety and still have trouble going to certain places alone.

I'm a very conventionally attractive person and that was one of the things she yelled at him when he broke it off, she said he probably laughed at her weight with me and she kept calling herself a pig, but to make it clear he NEVER belittled her to me, nor he ever used derogatory wording or made fun of her, he's a very sweet person and at a point he loved her and I would never respect a man who would body shame anyone. She said she was going to completely change her appearance, and no one would recognize her.

Obviously, everyone is blocked on social media, so I didn't keep up with her in the last three years.

Well, today I set up my company's Facebook, and she appeared on people I might know, and I'm not gonna lie, I snooped. I was shocked to see she got all sorts of surgery. She documented it all. She got hair implants and a boob job. She got the bypass done, so she lost a ton of weight and is talking about soon getting the excess skin removed, lipo, and a BBL. Seeing this made me feel.... weird??... I can't explain what I felt.

Especially given the fact that she subtly references me?? She basically mentions a lot of things like "Don't ever let anyone make you feel less than", "Don't ever let anyone make you doubt yourself", "you're worthy, don't make anyone else believe differently" or says she hopes her daughter flies so high that no one can ever reach and hurt her.

Again, I'm not in competition with this woman. My partner and I are super happy together and I'm ultra confident in my looks, but I can't help but wonder why I was a little shooketh, since I NEVER attacked or made fun of her looks and I most definitely never messed with her since I wanted nothing to do with her in the first place.

Thoughts?? Edit: Melissa the reason I know it is about me is because when he broke everything off she mentioned herself that she would transform herself so no one could ever make her feel that way again and so no one "like me" could laugh at her. I never did!
