My bf is being different

Leticia

So what should I do beofre my bf would always sneak out to see me and we would just hang out for a bit before he had to go back but now when I ask if he can he says no it I don’t wanna and he just seems different I can’t really explain it and we haven’t hung out for 1 week so I asked if he could come over and he said idk even if I want too or just idk let me check my schedule oh I’m busy maybe next time
