Its tough to get used to that kind of thing. My long distance gf has quite a few issues which make so many things that everyone else takes for granted impossible or very difficult. And sometimes its easy to get frustrated and let emotions get the better of you(bad, bad, bad idea)

I am learning to cope with it, little by little. That is not something you do quickly, its a learning process. I guess in order to overcome problems like this it is necessary for both of you to dig deeper into what is the heart of your relationship. Once that foundation is unassailable you will be able to deal with whatever else comes your way.
