he's being distant?

this guy that ive been talking to more than a year, he says im worth the wait and stuff but he's been distant for like 3 days but has his location on snap? He never does, I mean i know we shouldnt stalk and stuff but he hasnt been ignoring me.. but why is he being distant and he hasnt been asking me how I've been but always snaps me... should I do something? I know sometimes we girls should initate the convo but idk i want him to first cause he's the one who's been distant..
