Well, in my last (short!) relationship I rarely got to see the guy even though we live in the same town. I got really frustrated because our schedules conflicted so much. I kind of acted the way it sounds like this girl is acting. I stopped calling and left it up to him to get ahold of me. Maybe not fair, but I got to a point where I just didn't care anymore. You need to spend some time together. Unless it is a long distance relationship you should be able to make time for each other.
