You’ll have the weigh the value of this relationship against the burden and expense of traveling to see one another, extended visits, time off from work. Sadly, even the really special connections end up being too burdensome long-distance. One person ends up feeling like they’re giving more, this and that. My advice is-if you’re a man, you go to see her as much as your time & budget allows you and don’t put the burden & expense on her to travel to you. She’ll respect you more for that and it’ll make for a more harmonious relationship.
