People seemed to enjoy the freedom with a celebrant as they could choose where to get hitched and what their service entailed, Mrs Abraham said.
Relationship expert and psychotherapist Chris Wood said all relationships encountered challenges. "There's a big myth in our culture that if you're struggling in your relationship you're with the wrong person. Relationships have particular stages and people don't really understand."
Everyone felt great at the beginning "honeymoon stage", she said. "Some of that is because we've got a wonderful cocktail of chemicals in our brain that makes us feel very good. The job of those cocktails is actually to bond us together with somebody," Ms Wood said. Problems usually surfaced when couples moved on from that initial stage.
Serial daters were also more likely to be less satisfied in their relationships. "What I've heard is that the more relationship you have, the shorter [the honeymoon period] lasts," she said.
