Its all subconciously translated in your post, and what you wrote. Also, the other thread you made that you should have combined with this one says pretty similar stuff, about how you're annoyed or bothered by some problem she creates for you. If the problem is big enough to make you ask how to fix it, its significant. You can't argue that. Little things, people just deal with. Big problems, people try and fix. Something one does that is annoying, makes the person that does that annoying thing, annoying themselves. Its coming from the person, its something the person does, so its part of them.
I don't think her interest is the point here. Its yours. If these annoying things are really bothering you as much as you say, are you just going to keep seeing this girl? My ideal gf wouldn't be so annoying as to make me go online and ask a message board how to fix it. If you really don't like this problem, and it isn't going to change any time soon, then either deal with it, or find a new girl.
