Just face it, you want to live one way, and she wants to live another. I've met other people, even other travelers, who I am so compatible in every way but one: different ideals of the future. I hate money, and just want to do what I do forever, but they have plans for the future. This makes us completely incompatible.
Let's say I moved in with a traveler girl who got an apartment, and I just want to live how I'm living but she has dreams of getting a college diploma and eventually a high paying job. That tiny difference turns into a huge one: I want to keep moving, she wants money. Do you think that will end well?
If you love somebody that can't live your kind of life, what's the point? Do you think you will be happy living THEIR kind of life just because of an emotion called love? If you know things aren't going to work out, sometimes it's best to sit down, talk things over, and if necessary go your own ways before it gets REALLY hurtful.
