Worried

So for the past few months there's been signs and literally every thing showing my bfs on meth. He denies and denies. Even when caught in the act. He's lied to me all the time. Well two nights ago he wanted to go somewhere and wouldn't let me come with. I believe he wanted to leave to go get high. Well anyways we got in a huge fight, he went home friday night. Barely said shit to me yesterday, just how i should come talk to him, like i should beg for him to be with me. But today i didn't hear a word from him and that's unusual. It's unusual because he literally wasn't online all day. It says active 14 hours ago. There's night where he stays up all night but he usually wakes around 3-4 pm the latest. So I'm worried. If he was awake he uses wifi he would be online to be able to message people. Ik meth makes you sleep for long periods but idk. Maybe he used more dosage. Im worried tho like his dad gets home around 3..i dont think he woud go by all,day without trying to wake him up. My boyfriend has been suicidal so like im worried...i haven't messaged him because he's not active and idk i just dont know what to do. I feel like if something happened tho his dad would contact me but then again his dad is tired of his shit and constantly fights with him
