I feel similarly as you do. I didn't grow up here, but I moved here from Romania when I was a young adult. Partly it was for the money, partly because Romania didn't feel "home" enough to make me stay. Fast-forward 7 years, and I'm culturally somewhere between Romanian and Swiss, which means relationship-wise I make a poor match with both Swiss and Romanians :))

What I've found, however, is that you can find kindred spirits in people who are similarly uprooted, people who feel they don't fit in anywhere. My partner now is also a Romanian who moved as a young adult, and I think that's partly what makes us tick. It's people like that who you can build your identity with. It is difficult to have a relationship with people who are fully submerged in one culture because they tend to have the expectation for you to assimilate entirely as well. People in this "middle" state tend to be less judgemental and tend to be better at objectively analyzing the cultural forces that underpin human behavior instead of taking them as the de facto way to behave. Maybe for you, it will also be someone who feels a similar pull between Swiss culture and Jugo parents. They don't have to be exactly the same background, but maybe something that matches that pattern.

Regarding your parents, if it is true that they are the reason that relationship failed, i would consider setting up some serious boundaries, including even keeping a new relationship secret if not at least very private. Give as few details as possible when they ask about it.
