My ex deleted his instagram?

so my ex and I dated for 3 years and broke up bc we couldn’t do long distance anymore. Both us of kept in contact after a year of no contact and were friends with benefits, just after a few months I told him we can no longer be friends with benefits bc I’ve been dating this new guy and things between us are going really well after about 2 weeks he deletes his instagram. why?
