My age isn't over 45 for the record?
Why does this guy ghost me? How can I contact him?

Just like if it was reversed, you likely won't get any "closure" because for whatever selfish reason (and they are being 100% selfish, not to mention disrespectful and cowardly), they won't talk to you. As hard as it is sometimes, you should just try to shift your focus on other things and try to forget you even met him. I have never got any "closure" from women who have ghosted me, and when you try you're "not respecting their wishes", which only makes you angrier, so best to just move on if you can. And it'll take time, especially if you feel disrespected also, which I do personally. But again, they are just being 100% selfish and not thinking about you at all, nor do they care in any way.
It's really sad that ghosting has become not just a thing, but common and "acceptable" now. Some people think nothing of it at all. It's the worst thing to do to someone. All so they don't have to deal with it at all.

What was the big misunderstanding?
Honestly? If he's not replying, you don't need closure.
You need to accept that he's not into you. Sometimes when you want something you start to make excuses for things which is what you're doing.
Ghosting means he isn't into you.
Well that's incredibly rude and mean. If he has a problem with me, he could have just said it
