WHAT DO I DO?!!

So on Friday after 3pm I have not heard from my boyfriend. He has not been responding nor has he been opening my messages. Not sure why this is happening but now he hasn’t spoke to me for the whole weekend. Like he went MIA on me. He’s been acting different lately. I have a friend who dated his brother so they all live together... she was saying he’s been home doing nothing. Playing video games and been quiet. So he’s not cheating or anything like that.... not sure what to do in this case. But ladies I’m hurt. Nbs
