I've met loads of amazing blokes travelling, but all are just free spirits and by definitition and situation, not potential keepers.
Going slightly off topic, I must admit that it's slightly funny/ironic that you are asking this whole question on a Travel site, where most people are free spirits, if you wish, anyway, and the type of people you have done as not potential keepers. Even ignoring the fact that lots of people post "i want to travel, but my partner can't go, and i don't know what to do" type questions, and we all always say "go, travel, leave your partner!".
As such, are you really sure you want to be getting advice off us lot???
Anyhow, regardless of what you decide, best of luck and less us know how you get on!
Gelli has a point here. A lot of peopleusing travellerspoint will be the free spirit type, single and travelling etc. I know a lot of you are of happy couples. But I know a lot of you will also be happily single. Thats been my life for the past few years, but I don't see that there is necessarily a partner/travel divide. I've already said the guys I've liked best are the guys I've met travelling cos we've had most in common.
Right now I am committed to doing other stuff, here in Sheffield, for the next few years- ie nursing, which I honestly love, but unfortunatly I just can't travel for a bit, other than maybe a weekend away if I save. Yet I don't see that as a problem, sure I'm going to be skint for a long while, but i will be able to travel again. I've travelled both alone and with a partner, both had their strenghts and weaknesses, but whatever happens, I am addicted to travel, as are a lot of people out there, and it means a lot to me that I could find someone I could travel with, however that may be.
I think what Gelli was saying is, you can expect a more cynical attitude from people on a website like this because with travelling, being independent is really important to a lot of people. He's not wrong. He knows his onions, that lad.
