I’m so confused...

I don’t really write about my personal life, but I’m just confused and don’t really have anyone to talk to.

So there’s this guy that I’ve had a huge crush on since the day we met (which was over a decade ago) I never told him how I felt because at the time he had a gf. We recently reconnected, but now I moved out of state and we were catching up on things l, you know the usual talk and all.

Then he told me about how he really felt about me since the day we met. Then I told him that I had a huge crush on him too and we were both totally shocked about how we felt about each other, but we never told each other. Well time passed by and we’ve been talking non stop and flirted a lot.

Then a couple of days ago he texted me saying that he couldn’t stop thinking about me and that he wanted to see me. And now he’s been kinda distant from me, I’ll text him saying heyyy and how’s your day and he’ll say hey back, but after that he never replies back anymore.

Did I do something wrong? I feel kinda hurt... upset a little... I mean he was the one that said he couldn’t stop thinking about me and that he wanted to see me?
