Travelling isn't, either, found that the ward way during the last few years. If anyone has a good-ish solution for how they've handled that, feel free to share.
You mean the costs? Travel is expensive but I don't think there's much of an argument that it's gotten more expensive like housing. International flights used to be quite a luxury, now it's so easy that the popular destinations are getting swamped.
Most of the relaxation-oriented holiday industry is definitely designed for couples and families, but backpacking, adventures, and cultural immersion are, in my opinion, better alone so that you don't have the easy escape of sitting around with your partner. And if you want to relax nothing's stopping you from booking a few nights alone at a Japanese onsen or one of those treehouse style resorts in a Central American rainforest. I've spent many nights at onsens in between more outdoorsy climbing and skiing legs of trips in Japan.
Hmm I think this depends alot on the individual and their particular life situation though. I've done a ton of travel solo over the years and the vast majority of the time it was really fun.
You need to provide more information about your specific problems. Last I checked, two seats on a plant cost twice as much as a single one. That can't be it.
A hotel room for one is not two times cheaper compared to a hotel room for two, and accommodation is a big part of the cost when travelling. Also, when travelling in two and going by car you can share the costs, not all travel is airplane-based.
