The only "commitment" that really carries any weight is marriage. Even engagement is just a state of mind that can be broken at any moment without legal entanglement. Unless at some future point you two can live in the same city (not the same apartment, that would only come later after dating each other IRL for a while) it's pointless to talk about "committing". You just don't know each other well enough yet for any of that. It's very easy to present your finer points in an LDR. You won't know enough to put you credit/finances into each other's hands until you've been in the position to date in person for a significant period of time. Maybe find a diplomatic way to let her know that she's rushing things (and also that a verbal agreement is irrelevant).
