Being single used to mean that nobody wanted you. Now it means you’re pretty sexy and you’re taking your time deciding how you want your life to be and who you want to spend it with. -Sex and the City by deeplifequotes, via Flickr
Friendships change over time. It doesn't mean you have done anything wrong. It doesn't mean your friend has done anything wrong. Stop trying to figure out what you did wrong or blame the other person. Remember the friendship you once had as around memory.
