Testing out my crush to see if he cares a bit about me so I lied and told him I was going on a date with a guy and his response was “Ohhh”. He

You are in your 30's and still act like in your teen years? As much as I love living my teen years that I have lost, as much as I would never put myself in your position.
If my crush really wants me he would do an effort and if he wants anybody else who is immature and will only crash his world down, rather than make him grow like I would, then I let him have her, I would even open the doors for him to get her, I would ask help from everywhere to give whoever he likes a chance to be with him, if that's what he wants and what the people around him who made him believe the opposite about me, would want, I would give it to him, because if he was meant for me, he would be running to hug me, not walking away from me and running directly to her.

You going about this all wrong.

Guys are bad at receiving hint/clues and so are girls sometimes so he could be mad or jealous or sad or happy for you or just not like u like that

So you are a game player and a liar. Hopefully he does the right thing and ghosts you.

If you don't have an honest relationship with him, and have to "test him", in my opinion there's nothing there for you anyway so I don't see why it even matters.

I can tell you from experience. Men are terrible at responding to cues from women. If you're crushing on him, you need to let him know.

Maybe he didn't think you and he were 'exclusive' yet? crush doesn't mean relationship.

That's wrong to do
