Obviously, it won't work if either of you aren't interested in developing a strong relationship. But then again, that's how it is with any relationship, so this is a normal concern rather than an exclusive long distance concern.
Just like in any situation, just keep talking to her and get familiar and comfortable with each other. You can be a little assertive in your intentions, but don't push too hard (this is an odd kind of situation, after all). Time will tell whether or not things will work out like you want them to be.
