I’m freaking out right now please help

So my bf and i met on Tinder. We’ve been dating for five months now. I just decided to download the app because i wanted to see our first conversation to one another. I went to go look and i’ve checked in the past before but this time the conversation isn’t there and i’m not matched to him anymore.

Please someone tell me what this could mean. Did he unmatch with me so i cant see his profile? Did he delete his account? Would a deleted account erase your matches? Please i’m really so nervous now.
