When you are disappointed that he is called into the hospital, focus on what he is providing for someone in need.
What my boyfriend and I used to do when we were long distance is write really, crazy long emails to each other almost as long as my blog posts.
I had thought after so many years I would find a way to deal with the resentment. This girl is also a real person, not a caricature of a cult member, and even if the ultimate result is a breakup, she deserves to be treated with compassion and respect. Why shouldn't both people be responsible for making it work.
