I live in Sweden, my DP is Swedish and I have been here for 2 years now.
I am happy here but at the same time I do miss the UK, I am sad to say I have no Swedish friends, my DP has friends and I guess I am on friendly terms with his mates girlfriends but it's not like they would call me up and ask me to go out with them.
I have made some really lovely friends from all over the world, my closest friends are Spanish, Dutch and Australian. I live in Stockholm so it is easy to meet Englsih speaking people, Where do you live OP? If you are near Stockholm the meetup website is really good, also I met some nice people at SFI, it was hard to make myself go to Swedish lessons but I am glad I did.
When I go back to the UK it does make me realise what a lovely life we have here in Sweden, I think it helps that I have embraced all things some things Swedish, I love mushroom and berry picking, I have learnt to ski, who doesn't love fika! The weather is in my opinion much better than the UK, at least it doesn't rain for weeks/months on end.
I hope you find a solution that makes you all happy, I lived in Australia for a year with the possibility of staying there for longer but it just wasn't right for me. I felt no shame, sometimes a culture/country just doesn't fit with what you want from life.
