>>2 is right, even if you didn't fight how do you know they wouldn't have changed? Yes they're different now, but aren't you? Did you stay the same while they were moving on? Did you expect them to wait around, stagnant for you? Most people don't just freeze because they can't talk to their friends. They do what they can to feel a little better. If you are so worried about it simply asked them what has changed. I can't guarantee you'll like the answer, but at least it's something final.
