He stopped asking me to hang out?

We hang out once a week. This week he didn’t ask me once to hang out. I know he’s not busy because when I ask how his day was he says “fine. didn’t do anything interesting.” The conversations are still the way they always are, and as usual I always text him first these days and he replies eventually. He used to text first but then stopped after a while but we were still hanging out. Low key feeling like he was just using me.
