Many years ago I heard someone say that travelling can either make or break a couple. This phrase has never gone out of my head, and I truly can vouch that, for me at least, it has been very true.
Travelling does not only amount to jumping on a plane and grabbing some transport to click your camera at a few sites choked with tourists. It means planning. It means coordination. It means dedication and it also means taking into account the other person you are travelling with, especially when making decisions and prioritizing certain things over others. In other words, travelling with someone, be it a partner or not, is a metaphor for life with them. Can you move in tandem and pull the coach together as a team, or does one of you always need to hold the reins? Do you both share in the decisions together, or does one traveler bully the other into doing only what s/he wants?
I have gone abroad with a number of boyfriends throughout my life, and I’ve learnt a lot in all of these experiences. Travelling with someone seems to bring out certain traits which actually DO make or break a relationship, because when something like that is revealed, you start thinking about whether you really want to continue spending time with someone who for example, leaves everything up to you instead of enthusiastically pitching in and making planning part of the adventure, or else someone who is so placid as to actually make everything seem boring and colorless. And yes, these things do tend to come out during a trip with someone.
My current partner and I have been together for more than 5 and a half years now, and I can truly say that one of the things which made me realized we were meant for each other was our total coordination and the fun we had while planning a trip, as well as, of course, the way we actually pulled the trip off. This was only one of the factors of course, but it was an important one, as it showed both of us how well we could work together, not just to plan a trip, but to plan our life together long-term as well.
There are people who prefer to travel solo, be they single or not, and I respect and even admire these people as they really know what they want and have a great sense of adventure. I myself traveled alone many times (my first trip abroad in fact was a solo venture, as I went to Belgium for three weeks while attending a university course sponsored by the European Commission) and I found it liberating and relaxing too. However, once I had found my perfect match, I started to prefer travelling with him, as the experience was so much fun when we were together. However of course that is just me PLUS it does not mean I never travel by myself (I usually have to for work-reasons anyways) or will never do so in future either. After all, an adventure is an adventure!
