Intuition is always right, it is what you hear and actually, we all know that in the end it ture.
But trusting it is not always an easy part, often because it is in battle with the way it is and it often doesn't seem like it.

For example :
You feel that a person is not good for you but he or she is really kind and open to you but still, you have the feeling that something is not right about the person.  But after all, you become friend
A few weeks later when you want to hang out with the other person you get only texts back: I can't go I'm sick but the same day you figure out he or she is with other people and not telling you this. The person is not talking to you anymore and you feel alone and confused.

Of course there are other examples, but this is just a short example of how intuition works.
It is important to trust your intuition and to believe your feeling is right even if it is not in line with what already is. Mabey I said it before but the intuition is not acting out of fear it is acting our of learning and trusting yourself and it pops-up in situations you just don't expect.
If you know it is intuition but you feel a little bit of fear, you can think why you have fear it is it changing a situation or are you scared you are losing something?
The point is life is not about losing or winning it is about endings and beginning when you lost something or someone you will get something better back in return. Plus you finished something and learned from it so actually, we all should be proud of what ended so we can learn new life lessons.
