I would like to go back to my home country however my boyfriend doesn’t

My boyfriend of 4 years and I decided from the very start of our relationship that we want to leave our respective home countries (Greece and Malta) and live abroad to close the distance.

The original plan was that I go to Greece for my gap year to learn the language as it was always something I wanted to do and then for my boyfriend and I to work in Malta to earn enough money to move to Ireland. However, when time was approaching my boyfriend had told me he didn’t want to go to Malta and wanted to go straight to Ireland to do his masters degree. I could not afford to do that so we were at a distance for a few months until I got enough money to move to Ireland.

Fast forward to now, it has been a year and a half and we dont have any friends (we had from his course and they all left) and I really dont like it here. I dont feel like I fit in and I cant get used to the weather. I get homesick regularly and would love to go back home. However, my boyfriend is doing a PhD that will take 3 years to complete. I am willing to wait but he doesnt want to move to Malta at all. And with my job its very difficult to find something good in countries similar to Malta whereas he can most probably work remotely although he wouldnt want to. He tries showing me other places and I make an effort to look into them however he doesnt do the same for Malta as he says he is certain he wont like it. He had visited muktiple times however only for short stays, the max he did was a week.

I really love my boyfriend but I really miss my home, my family and my hobbies that I had there. Sorry for the long post but I dont know what to do and I would appreciate anyones advice! Thanks!
