How much time do I let pass?

I recently had an “argument” with a girl I met on Facebook like a year ago and we’ve been talking to each other pretty much every day since then. But of course like less than a week before I was going to go visit her for the first time in person, since she lives almost 9 hours away from me, there was a little confusion with a guy who she is kind of close to that lives near her. It’s one of those situations where it wasn’t really anyone’s fault and things of just happened. And I already know that she is kind of really going through a lot of crap lately, but I mean aren’t we all in some ways? I just don’t know if I should like ignore her for a while and kind of just let things settle down a bit or if just keep doing what I’ve been doing but dial it back just slightly or whatever. I’ve had so many people in my life though telling me that I should just let it go completely seeing as we’re doing the whole long distance thing. But I kind of feel deep down that I don’t want to do and want to at least stay friends with her and see what happens for the time being. It’s just that this is the first time I’ve really felt like this towards someone else and want to give it my all in some ways but also that even then things might not work out, and that there are plenty of fish in the sea. I just don’t really know what to do. I feel like if I still continue talking to her that’s I’ll feel like I’m starting to bug her but also just don’t want to give up on it either. I guess mainly I just need to be patient and let things kind be as they unfold.
