Do you think he still loves me?

Im not sure if my boyfriend loves me anymore. Yesterday he went to the mall with his girl classmate without me. I heard the plan from that girl by the way he didn't even tell me that he was gonna go. The other day i told him that i was gonna meet with a guy friend and he only said “ok” He doesn't text me as much as he used to do and i dont text him neither. He acts normal towards me at school but i feel like if i break up w him he wouldn't even be sad. What should i do?
