You may not want it to happen, but it does; sometimes, you are simply too sensitive in your relationship. The problem is that the more sensitive you are, the higher the chances of getting hurt. Plus, if your sensitivity comes out negatively, you might make your significant other become frustrated and develop negative feelings as well. This is why you need to learn how to stop being highly sensitive in a relationship. For the sake of your relationship (and let's face it, your sanity), you need to learn how to control your emotions so that both of you can be happy.
