I'm sorry you are feeling disappointed by your friend locust. From your concern, I get the sense that you have maybe been friends for a long time. It sounds to me that you and your friend are on different wavelengths. Whatever the reason she may call you less and want to spend less time together, I wouldn't necessarily try to guess why. There could be so many reasons. Even if she just was busy, it sounds like her friendship style doesn't make you happy or fulfill your desire for companionship. While I know this is tough, I would try to just accept the relationship as it is - tell your friend how you feel, full out. You don't have to threaten to end the friendship, but just say: hey, with the rate at which you call me and see me, I feel that you're not supporting me as a friend, I feel you don't care about me. Then you will feel so much better because your feelings will be off your chest. Go ahead and find a friend who does give you what you need. As they say, you can bring a horse to water, but you can't make it drink.

Nevertheless, it is natural to feel hurt about this type of situation. Just remember that this relationship does not define you.
