best friend list

i accidentally glanced over at my boyfriends phone earlier and noticed his entire snapchat best friends list is girls…. i know he HARDLY uses snap except with me so that’s not the issue and i know he just restarted streaks which kind of bothered me and the fact they are all girls…… his comment back was “i don’t even text them…” like that’s not the principle…. i don’t do that to you because i respect you and know how you would feel…. i walked out of the apartment and went to work without speaking to him and i don’t know what to do…
