Is he ghosting me or should I be concerned?

I’m writing here cause I have nowhere else to post it and I’m lowkey concerned.

I’ve been texting this guy for a couple of weeks. We text a lot but for me it’s mostly physical. He works few hours away and the day after tomorrow he has to leave again for work (summer job in Spain).

That’s why he proposed to come to me today, we could spend the entire day together since we won’t be able to until September (we leave in the same city but he has summer jobs outside of the country). It will be mostly sex of course.

I asked him for confirmation that I should cancel my other plans today many times and he agreed every single time the past few days.

This morning I get a “good morning princess” text etc and then he tells me he arrived at the train station, sends messages and audios etc. The train station is like 20 minutes away from my house (didn’t give him my address yet but he knows the metro stop).

Now, it’s been three hours and I haven’t heard from him. He hasn’t blocked me or anything but even Instagram calls don’t land, it’s like his phone has no data or no battery.

It’s been so long I’m starting to think he’s just ghosting me but then why telling me he’s at the station this morning? Another part of me is concerned now that something happened, he did sound super tired in the voicemails and idk what to think

Advice? Should I just plan something else today? Or should I keep contacting him?
