Realizing you were never your exes type

I ended up finding my (22F) exes (24M) TikTok as my TikTok is linked through my contacts. I checked the account and just out of curiosity I checked who he was following. I realize now it was a mistake.

Back when my ex and I were together he made negative joke about how small my chest was despite telling me he loved my chest throughout our entire relationship. He ended up apologizing for it but the comment hurt me for a really long time. When I checked his TikTok I saw that he was following onlyfans models who had larger chests than me, and it made me feel like he choose these onlyfans models over dating me because I was never his type. I gave him love and all of me but I was never enough for him because of how I look. He still try’s to reach out to me now and then, but I don’t understand why because I will never look like these girls he follows.
