Why don’t you want to give it a try? See if you might like the country he is going to?
I met my partner in a country we both are not from. I got PR before moving so slight difference there, my partner was on a work visa and once it ran out, we did long distance for a year and a half. We are now moving back to my home country. I would definitely move to his country if that’s what he wants.
That seems similar to my situation. My partner was not ready to commit to a place, I was not in his future plan and I couldn’t move at the time (waiting for citizenship), hence why we did long distance. We practically took a break there while he went back home as his work visa ran out and he didn’t want me to sponsor him.
I believe if it is meant to be, it will be. We continued keeping in touch and took turns visiting each other for a year and a half. We weren’t interested in dating other people so it was ok.
Then we decided it’s time to have a baby and planned our next move. My son is now 6 months old and we are moving back to my country. We have about 4-5 years before our baby goes to school to decide where to settle so plenty of time.
