Ugh:( need enthusiasm!

Feel so bleh lately! He hasn't replied to my message in 3 days (I know it doesn't sound a lot but he lives in a different country)
I know he loves me etc etc (he's trustworthy and would never tell me that if it wasn't true) but honestly I just miss him 😞 he's home in a few weeks and I want to talk about it with him and get excited together but it seems I'm not worth his time?
He tells me not to read into anything too much and then he goes and does this - what am I supposed to do??
Just feel a bit crap atm tbh..
