If you block an account on instagram, you can still see your DMs with them (this also works with a deleted profile). If the dms really aren’t there anymore, he deleted them because he didn’t want you to see.

Like why did you pick the name Jyke..

Anyway, I think you should meet him and see what their dynamic is like. Its really hard to give a definite answer without knowing any information about them. Also how long did it take them after meeting to decide to be just friends?
