Remove ex from socials

Would you say it’s petty to unfollow my ex fiancé on insta? It was a mutual decision to split and remain cordial with each other and agreed since it wasn’t a bad breakup to still be mutual son social media. Well it’s only been like 2 months and I see he’s already added all these random girls and I know he’s free to do whatever but it’s almost makes me feel/stings that I wasn’t THAT important to him to begin with and ask to marry if he’s already following random girls? Last thing I want is to see him post a pic with his new chick already. I guess it shows who’s healing and taking time vs. needing distractions?
