Advice?

I have been talking to this guy for a while, he’s been different with me lately idk he used to ask to see me/hang out all the time but now he doesn’t, I am so used to talking to him every day, we have a 200🔥 streak. Not talking to him gives me anxiety but talking to him and feeling him changing also hurts me. Today I decided not to talk to him to see if he would talk to me but he hasn’t yet, should I?
