I broke up with my ex nearly two years ago and we haven’t spoken in a year.  

Two days ago he messaged me out of the blue and just genuinely seemed to want to know how I was doing and wanted to apologise for some things that happened in the relationship.

I thought it was really kind, and I messaged back apologised too and we kind of bat a few messages back and for about two hours just catching up a little bit.   Then out of nowhere he just stopped replying.

For once in my life I’m 100% certain that nothing bad happened and nothing was too full on either.  His last message was actually him asking me a question and seeming excited to catch up but it’s been two days now and he’s not replied to what I wrote even though he was replying quickly before.  

It leads me to these points -

**Did my message not go through?**
I was texting him from my iPhone to his non-iPhone in a different country.    Because of this it’s all green texts and I can see delivered/read receipts.    If the text message didn’t make it, would I be notified in some way?

For my last text I was in an area with slightly less than ideal signal, but still able to send messages to other people, albeit via snapchat and not text.  Is it likely the message to him bounced and didn’t go through?  I don’t want to look ignorant.  

Or is it more likely it went through and I got ghosted?  

I feel like it’s a ghosting situation but I don’t understand what went wrong.   Maybe he got scared and backed out?  I’m not sure.  Everything seemed absolutely fine.  Agh!

I don’t want to double text him in case he really decided he didn’t want to talk, but I also don’t want to seem ignorant if my text didn’t go through.  

Can someone help lol?   I’m fairly certain I’ve been ghosted but I dunno.
