Was I blocked on the app LINE?

[AC Question]

Ive been talking to a guy for a littlw over a month. Every day all day. He deployed to afgh. About a week ago (its legit no catfish!) And has been using a sim card to talk on LINE. I sent 2 messages, they've never been read, i logged on 2hrs later and it said "..has left the chat" and it says empty room abd unknown where his name used to be. Did he block me out of the blue??
