We've been together for four years, lived together for two then decided to live separately this past year. Two houses away from each other! And it has been a great move for our relationship which has never been better. Both in our mid to late thirties and no children. We get quite a lot of raised eyebrows and some judgy comments especially from his side of the family who are very traditional. We're not too bothered about that most of the time though I do occasionally lose my cool and struggle to keep a sense of humour at long periods of time spent with the in laws. But other than that I don't see any good reason (unless we had children) not to carry on as we are indefinitely.
Anyone else in a similar situation?
