of course it's possible, but not every relationship is has 'the right stuff' to keep it going past a certain point. You have to know what you want, why you want it, and how to get it and your partner has to be on the same page as well (shared goals, values, similar life-stages, etc). Real, stable, healthy, functioning adult relationships require a good deal of actual effort, and not everyone wants to do the work necessary to sustain them.
